Merge branch '20189-markdown-video-doesn-t-work-when-the-referenced-video-file-is-in-same-repo' into 'master'

Ensure relative paths for video are rewritten as we do for images

## What does this MR do?

This ensures that path to videos are rewritten as we do for images.

## Are there points in the code the reviewer needs to double check?

I've decided to add a new `Blob#video?` method for simplicity's sake but this should probably be added to `Gitlab::Git::Blob`.

Fixes #20189.

Disable MySQL foreign key checks before dropping all tables

Fixes #20237. Disables MySQL foreign key checks before dropping all tables in a restore. MySQL doesn't honor `CASCADE` without a special flag when the database/tables are created. In order to drop the tables we need to disable foreign key checks. After the drop, re-enable the key checks. 

WIP: Pending confirmation from customer that this fix works. 

See merge request !5472

This significantly reduces the DB churn in the PostReceive task when it

Fix CI status icon link underline

## What does this MR do?

Changes the CSS so that CI status icon does not underline when it is hovered over.

## Are there points in the code the reviewer needs to double check?

Just need to make sure there aren't any side effects (`.ci-status-link` being used without an icon).
To my knowledge, every instance of `.ci-status-link` is tied to a `.ci-status-icon-{statusName}`.
