MR Review: indicate which changed files have MR discussions

Problem to solve

When I'm reviewing MR's I don't know which files have MR discussions before I show the diff and scroll to the comment.

Proposal

I propose the same solution as GitHub Pull Request extension uses. Add a text bubble emoji decoration the same way we add decoration for the type of change.

Extension_Development_Host_-_webview_controller_js___gitlab-vscode-extension-TEST_and_extension_js___gitlab-vscode-extension

Further details

GitHub Pull Request Screenshot

Getting_Started___github-test-repository

Links / references

I created a POC, the change seems fairly simple https://gitlab.com/gitlab-org/gitlab-vscode-extension/-/commits/commenting-decorator-poc
