The base theme stable is not operated correctly

Reviewed and looks good to me.

Can be moved to RTBC

So, my understanding is that this change switches to using core's stable9, rather than the contrib stable theme. I'm fine with this (especially if the contrib stable theme wasn't installing correctly anyway). Essentially using option 2 rather than option 1 from this page https://www.drupal.org/node/3309392 → .

In your testing, did it seem like this switch introduced any issues related to the differences between stable and stable9 that that documentation mentions?

@sim_1 When we install Drupal "10.0.x", the "stable9" theme exists on the "core/themes" path. So there is no need to add an additional contributed project theme "stable".

The contributed project theme "stable" will effectively work the same but it's now dependent on something outside of Drupal core.

I have checked with the Option 2 approach and the site is working fine with that. I have not found any issues from the UI side.

Great, thanks for checking. I think it's most important that we having a working install so hopefully we can just patch any visual issues that come up if we do end up encountering any. Thanks!

Great, thanks for this MR and testing! Merged.
