Missing `Special GitLab reference` for a link to a line of code

Summary

There is no Special GitLab reference for a link to a line of code (e.g. this). When I paste a URL to a line of code into a comment, it does not render in any special way – the hyperlink text is the URL. Such a hyperlink is hard to read, takes a lot of space and this behavior is unexpected as for example MR, issue or commit URL renders as Special GitLab reference.

Steps to reproduce

1. Input URL to a line of code to a comment (e.g. https://gitlab.com/gitlab-org/ux-research/-/blob/master/Survey%20about%20requirements%20for%20monitoring/Features%20list.md#L8).
2. Click Preview.
