#59223: Block styles missing when using symlink and separate core block assets

 I noticed core block styles were missing, but only on production/staging.
 It could be temporarily fixed by setting the
 `should_load_separate_core_block_assets` filter to false or by deleting
 the transient `wp_core_block_css_files`. This is what I found out:

 The theme was a custom block theme, but even after switching to Twenty
 Twenty Three the problem remained.

 I am deploying my sites using Trellis: there is a release directory for
 every release, and `current` symlink that will be updated once the
 deployment succeeded.

 After deploying, I also pushed my database and search/replaced URL/Domain.
 The path to WordPress stays the same (`/srv/www/examplesite/current`),
 with one difference:
 Locally, `current` is an actual directory.
 On the remote server, it is a symlink pointing to the release (e.g.
 `/srv/www/examplesite/releases/20230828160120`).

 That seems to break something in the function
 `register_core_block_style_handles`.

 After deleting the transient `wp_core_block_css_files`, it works again.
 The transient is deleted during WordPress upgrades.
 Example before deleting:
 {{{
 $ wp transient get wp_core_block_css_files
 array (
   0 => '/srv/www/examplesite/current/web/wp/wp-includes/blocks/archives
 /editor-rtl.css',
   ...
 }}}

 Example after deleting/regenerated version:
 {{{
 $ wp transient get wp_core_block_css_files
 array (
   0 => '/srv/www/examplesite/releases/20230828160120/web/wp/wp-
 includes/blocks/archives/editor-rtl.css',
   ...
 }}}


 I know this is very much an edge case, and you're probably supposed to
 delete the transients anyway after migrating a database. But still, I
 wanted to report it.
