Change "spaceless" tag to filter

Problem/Motivation

Apparently the {% nameless %} no longer works for Twig 3. One of my Drupal 10 installations threw all kinds of php errors*

Proposed resolution

See issue 3380774 🐛 Spaceless Tag is Deprecated in Drupal 10 Fixed and the Symfony documentation:

• Change all spaceless tags in the templates to apply spaceless
• Change all endspaceless tags to endapply
• The same applies to Seven → , which also uses some Classy templates

I've no idea how to make patches, but since I've already fixed the affected local templates I can just zip them if the devs are interested.

* For Google's sake: Uncaught PHP Exception Twig\\Error\\SyntaxError: "Unexpected "spaceless" tag (expecting closing tag for the "for" tag defined near line 27)." at [path theme] toolbar.html.twig line 30'
