New settings not in layout_details

Moved it in the layout_settings wrapper as the name changed a little on commit.

@tim-diels, thanks for your MR. I can see the test has failed.

I will fix the test first and then back to this issue.

When using the patch, I got the following error:
TypeError: array_filter(): Argument #1 ($array) must be of type array, null given in array_filter() (line 174 of modules/contrib/layout_builder_lock/layout_builder_lock.module).

I needed to add the #parents-configuration to the layout_builder_lock_regions form element to fix the issue.

You both were correct that the patch provided an error.

The extra code provided in #6 did fix the issue. Thanks for that.

Still needs testing then :)
