chore: use public repository URLs

[snkk2x-collab]

Summary

• Update package repository metadata from SSH-style GitHub URLs to public HTTPS URLs.
• Apply the metadata-only change to the commitlint config, prettier config, and VS Code extension pack package manifests.

This does not change runtime code, dependencies, lockfiles, versions, or entry points.

Validation

• Metadata assertion: all three changed package manifests now use git+https://github.com/yetanothercode/yet-another.git
• git diff --check
• yarn install --immutable --mode=skip-build with Yarn 4.9.2
• npm pack --dry-run --package-lock=false in:
  • packages/commitlint-config
  • packages/prettier-config
  • packages/vscode-extension-pack
• prettier --check on the three changed package manifests

Notes:

• Yarn install currently reports existing peer dependency warnings.
• There are no repository test scripts for this metadata-only change.
