fix: #3617362 Require a released Varbase Patches instead of the 11.0.x-dev branch

Issue: https://www.drupal.org/project/educare/issues/3617362

composer.json requires vardot/varbase-patches at 11.0.x-dev, so Educare cannot be installed on a released Varbase: the dev-branch pin conflicts with the locked, released 11.0.38, and composer require -W only resolves it by downgrading the site off released patches onto the moving dev branch. Neither is acceptable for a site template.

-    "vardot/varbase-patches": "11.0.x-dev",
+    "vardot/varbase-patches": "~11.0.0",

~11.0.0 resolves 11.0.38 and any later 11.0.x. No other requirement changed.
