Stretched links are used to make entire sections, like a card, clickable. See https://getbootstrap.com/docs/5.3/helpers/stretched-link/

Maybe @PhilETaylor can answer us about this (he made the original PR to add this in #49887) but I think it wasn't intended to make entire Twig panel clickable to open the template. So, in this PR I propose to remove this behavior.

Here you can see how in the Security panel, the link is not stretched but in the Twig panel it is:

I just copied and pasted code from elsewhere in the toolbar, sorry.

I never noticed this problem, but I can confirm it's not meant to be like this and needs fixing, thanks for correcting my bad code.

Since adding this feature though, it's literally been the thing I click most in the toolbar - its a real timesaver.

Phil, thanks for confirming this. So, then this is OK for review and merge. Thanks.
