Allow user to archive selected links

[mariomadproductions]

Is your feature request related to a problem? Please describe.
If a URL is on a page as plain text and not a link, it can't be archived as easily as a linked one.

Describe the solution you'd like
If text is selected and contains a link, archive that instead of the current page when using the right-click menu. I guess if the text contains more than one link, just use the first one.

Describe alternatives you've considered
Using an extension to link all URLs, but I don't want to do that.

Additional context
None
