I was unable to find an issue or PR which mentions this.

Extensions with non-GitHub repository links always use the GitHub icon,
which is inconsistent with the changes merged in #44738 and #57500. This
change makes `extension_ui.rs` use the Git hosting provider registry to
determine these icons. Below is a preview of the change:

    />

Release Notes:

- Improved extension repository links to show provider-specific icons.
