[FEATURE REQUEST]: Add Context Menu Item to Search ...

I really would LOVE if there was a context menu item that searches my Wallabag for the currently highlighted/selected text.

For example:

Selected text -> General Search:
`https://redacted.com/wallabag/web/search?currentRoute=search&search_entry%5Bterm%5D=`

Selected text -> Tag Search:
`https://redacted.com/wallabag/web/search?currentRoute=tag&search_entry%5Bterm%5D=`

This would make my life easier on so many levels! :D
