feat!: bumping eslint to v10 (W-23473845)

[jfeingold35]

Part of @W-23473845@, the conversion of OCLIF to ESLint v10.

Process:

yarn add eslint@^10
yarn add eslint-config-oclif@latest
yarn lint --suppress-all
# manually fix one errant inline suppression
git add package.json yarn.lock src eslint-suppressions.json
git commit -m "msg" --no-verify # need this because the verify will try to apply breaking auto-fixes to the file I modified
git push
