docs(lstk hotfix): update CLI reference to v0.22.0 - #850

Brings the lstk CLI reference docs up to date with the v0.22.0 release of localstack/lstk, catching up the full backlog from the last-documented v0.19.0. This PR started as the v0.21.0 sync; it now also folds in the v0.21.0 → v0.22.0 delta, so it covers the whole v0.19.0 → v0.22.0 range (v0.20.0, v0.20.1, v0.21.0, and v0.22.0) verified against the CLI at the v0.22.0 tag. main was merged in so the diff is a clean superset of the current docs.

Reference pages in scope

• src/content/docs/aws/developer-tools/running-localstack/lstk.mdx
• src/content/docs/azure/developer-tools/lstk.mdx

There are no shared lstk components yet, so each page carries its own reference content and both are kept in sync.

What changed

v0.21.0 → v0.22.0 (new in this update)

expose_ports config option (localstack/lstk#433) — added to the default config.toml snippet and the config field reference table on both pages. Documents the grammar (a bare port, or a Docker-style "[host:]container[/proto]" string; an entry with no protocol publishes both TCP and UDP) with the DNS-server ([53]) and "5354:5353/udp" examples. This is the config surface previously tracked in DOC-392; that change never landed in main, so it is consolidated here.

lstk aws --account (localstack/lstk#440) — the aws proxy now accepts a leading --account <12 digits> flag (default 000000000000, falling back to the ambient AWS_ACCESS_KEY_ID), matching the flag lstk terraform and lstk sam already expose. Added an options-table row, an example, and a short note that lstk cdk deliberately has no --account.

Not documented (verified out of scope for these two reference pages): the extension-context additions endpointUrl/machineId (localstack/lstk#446) live in the extension-authoring contract, not the CLI reference; the lstk start invisible-re-login fix (localstack/lstk#449) only fixes behavior the Offline/enterprise section already describes; telemetry exit-code recording (localstack/lstk#396) is internal.

v0.19.0 → v0.21.0 (carried from the earlier sync)

• Authentication order reversed (Prioritize LOCALSTACK_AUTH_TOKEN over stored credentials lstk#415) — LOCALSTACK_AUTH_TOKEN takes precedence over a keyring token; the resolution list, caution box, and env-var table were corrected.
• --endpoint-url / LSTK_ENDPOINT_URL (Add --endpoint-url flag to target externally-managed emulators lstk#419) — new "Targeting an external emulator" section plus Global-options and Environment-variable rows; documents which commands accept it, which reject it, http/https handling, and emulator-type auto-detection.
• container_name config field (Support a custom container name in config lstk#420) — added to the config.toml snippet and the config field table.
• snapshot versions + version-pinned refs (Add Cloud Pod version listing and version-pinned snapshot loads lstk#430) — new subsection; subcommand count five → six; load/show document the pod:<name>:<version> suffix.
• Container runtime auto-detection (Auto-detect Rancher Desktop and Podman container runtimes lstk#399, Fix broken Lambda debugging link #422) — reworked the runtime-discovery paragraph and the "Port 443" and "Docker is not running" troubleshooting entries; fixed the Azure page's type = "azure" example.
• Smaller items — lstk logs streams to terminal scrollback (Stream lstk logs lines to real terminal scrollback lstk#418); lstk az consumes its own --non-interactive (Honor lstk's own flags for lstk az instead of forwarding them to az lstk#431); lstk aws <TAB> completes AWS commands (Add shell completion for lstk aws lstk#424); binary self-update verifies its SHA-256 checksum (Verify release checksum before replacing lstk binary lstk#410); removed a duplicated setup azure subsection on the AWS page.

Review

Advisable. Most edits are mechanical reference updates, but a couple touch user-facing wording worth a glance: the reversed auth-token precedence (a behavior change users may have scripted around) and the "Port 443" drop-with-warning framing.

Closes DOC-393
