Extra tooltip script on user menu should move to admin.css

[deanmarcussen]

Describe the bug

We have an extra script that was added to the UserMenu to provide tooltips.

<script at="Foot">
    $('[data-toggle-tooltip="tooltip"]').tooltip();
</script>

We should move that script to the admin javascript, because it's just an extra script being loaded on every page on the admin, when it could just be part of our normal admin javascript.
