Comments: Limit comments shortcut to not execute on links.

Exclude links from activating the comment submission shortcut.

[45790] introduced a shortcut to submit comment forms using `Ctrl/Cmd + Enter`. This keyboard combination is also the combination for opening a link in a new tab, which resulted in submitting the form when using the Log Out or Edit Profile links.

Fixes #61919.
