Commit SHAs are not highlighted and hyperlinked when comments are rendered in-line in the file viewer.

This works as expected in the PR description view:

- Extension version: 0.108.0
- VSCode Version: 1.99.0-insider
- OS: macOS Sequoia 15.4
- Repository Clone Configuration (single repository/fork of an upstream repository): Single repository
- Github Product (Github.com/Github Enterprise version x.x.x): GitHub.com
Steps to Reproduce:
- Create a pull request review comment in GitHub which references a commit SHA
- Open the PR's description view in VS Code. The SHA is highlighted and hyperlinked to the commit on GitHub.com.
- Open the file view in VS Code. The SHA is not highlighted or hyperlinked.
