[ansible-galaxy] Remove role name conversion when the repo startswith 'ansible-role' (#82508)

* Remove role name conversion based on whether the repo name starts with
ansible-role

This was added in 2.3 to match the Galaxy ui behavior of truncating the
'ansible-role-' prefix automatically, but the new backend requires an
alternate name to be provided or defined in the ``galaxy_info``
metadata.

Roles that were imported using the ansible-role-$name convention will
need to use ``--role-name`` or add ``role_name`` to the ``galaxy_info``
dictionary in ``meta/main.yml``.

changelog

* Update changelogs/fragments/fix-default-ansible-galaxy-role-import-name.yml

* Update changelogs/fragments/fix-default-ansible-galaxy-role-import-name.yml

+    ``ansible-galaxy role import`` - fix using the ``role_name`` in a standalone role's
+    ``galaxy_info`` metadata by disabling automatic removal of the ``ansible-role-`` prefix.
+    This matches the behavior of the Galaxy UI which also no longer implicitly removes the
+    ``ansible-role-`` prefix.
+    Use the ``--role-name`` option or add a ``role_name`` to the ``galaxy_info`` dictionary
+    in the role's ``meta/main.yml`` to use an alternate role name.
