chore(deps): bump @opentelemetry/core and @c15t/react in /docs

[dependabot]

Removes @opentelemetry/core. It's no longer used after updating ancestor dependency @c15t/react. These dependencies need to be updated together.

Removes @opentelemetry/core

Updates @c15t/react from 1.8.5 to 2.1.0

Changelog

Sourced from @​c15t/react's changelog.

2.1.0

Minor Changes

• 4a89092: Expanded the script loader with a registry-backed provider system and a much broader set of consent-aware integrations. New helpers cover analytics, advertising pixels, functional tools, and tag managers, including Ahrefs, Cloudflare Web Analytics, Fathom, Hotjar, Matomo, Microsoft Clarity, Mixpanel, Plausible, PromptWatch, Rybbit, Segment, Umami, Vercel Analytics, Reddit Pixel, Snapchat Pixel, and Crisp/Intercom.

  Provider manifests now share common utilities for script URL resolution, boolean data attributes, install-step builders, Google consent mapping, and lifecycle execution. The package also includes registry metadata, focused provider tests, and engine coverage so script helpers resolve predictable loader URLs, attributes, consent callbacks, and queued vendor calls.

  Google Tag and Google Tag Manager boot timestamps now resolve during script lifecycle execution instead of helper construction, which keeps documented setup patterns compatible with Next.js Cache Components prerendering.

  PostHog now supports explicit EU/US region selection, keeps the bootstrap script host aligned with an explicit API host, and exposes loading modes for immediate cookieless consent sync, consent-gated loading, or disabling the helper without issuing a PostHog network request.

  Updated the docs and CLI generation prompts so these providers are discoverable from the integration docs and script-loader setup flows.
