Fix `Failed to resolve directive: gl-tooltip` console error

What does this MR do and why?

Related to #328615 (closed)

There was an unneeded v-gl-tooltip in ee/app/assets/javascripts/pages/groups/saml_providers/saml_members/index.vue#L44 that was causing console errors. This MR removes that unneeded v-gl-tooltip.

It appears that this v-gl-tooltip has been in the code since this file was originally committed so I don't think it was intended.
