Add a template for a key value pair

For an initial starting point of what I mean, I've added a patch of my changes to get this working.

Updated patch, seemed broken.

Can confirm above patch works on Key Value Field version 1.3.0 (and Drupal 10.4.1). Thanks!

We've also had success with the patch in #3. We're running Key Value Field version 1.3.0 (and Drupal 10.5.0).

My only comment is the theme hook is using key_value namespace, which doesn't really belong to this module. Although it's already using it for the field formatter, so in that way the ship has sailed. It's also true that the key_value module → doesn't overlap in use case at all, so it's probably fine.

Marking RTBC.

Looks like the tests will need to be updated/expanded for this to go in. You'll notice a few commits here but that was a mistake, ahh patches ;).. anywho, once those tests are fixed this looks good to me.

Working on this!!

Hello @japerry,
When i rebased the MR to check if there any other tests that might cause errors in future, the MR became empty and it is not showing any changes that are to be committed, also i cloned the repo and ran pipeline on local but it is passing without any error.
So could you please help here.

Also when i am going to the commit fc5be3ffdcca2be09754da0e82cd16c211ae2f6c then i am able to reproduce the phpunit errors on my local but there is an latest commit which is reverting this commit that is why MR is coming empty should i reset the forked branch to this commit Issue #3437567: Add a template for a key value pair
Thank you!!
