Resolve "Tooltip Consistency"

Closes #61821

See merge request gitlab-org/gitlab-ce!28839

On edit-button simply set position to top.
Made this change directly in template since edit-button
is only used in one place.

Had to wrap the comments toggle button in span tag to make
tooltip show even when disabled as per bootstrap-vue docs.
https://bootstrap-vue.js.org/docs/components/tooltip#overview

Note: Also changexc button to gl-buttonto be consistent
with rest of file.

without leaving MRs with a stale merge-ref.
