Script Loader: Remove erroneous `type` attribute from `script` tag wrapper on login screen.

This was causing a `_doing_it_wrong()` notice from `wp_remove_surrounding_empty_script_tags()`. In fact, the `type` attribute was added in [56748] to test this incorrect usage notice. This commit reverts that change.

Follow-up to [56748].
Unprops westonruter.
See #58664.
