Fix markdown anchor icon interaction

## What does this MR do?
Fixes and improves the markdown anchor icon interaction so that hovering over any headers (generated through markdown) will have an anchor icon that's easily accessible (won't hide from you on edge cases), replaced the icon with fontAwesome icon and added more padding for the anchor icon.

## Are there points in the code the reviewer needs to double check?
1.  Need to check if it's okay to replace the icon-link.png with fontAwesome
2. Need to check if it's okay for the additional view padding on views that render markdown to compensate for anchor link space
3. Need to check if there are any other views that render markdown that did not have it's padding re-adjusted

## Why was this MR needed?
Improve markdown rendered anchor links so that they are more user friendly

## What are the relevant issue numbers?
Closes #20459

Fix expiration date picker after update

@DouweM this object is now on `gl`, not on the window. It would only break when trying to use the date picker on a newly-inserted member element, but I figure it's probably worth sneaking into a patch.

Handle error on trace raw download with old builds (DB stored)

## What does this MR do?

Handles error on `raw build trace` download action for old builds (which are stored in DB instead of file).

Front End - Rewrote ES5 `user.js` to ES6 `user.js.es6`

## What does this MR do?

This MR removes the `users.js` file in `app/assets/javascripts/users.js` and replaces it with ES6.

* It also adds the file extension `.es6` so that the sprockets babel gem can transpile it to ES5.
* The new file is: `users.js.es6` in `app/assets/javascripts/`
* Replaced `new User` with `new gl.User` in `app/views/users/show.html.haml`

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

I followed the AirBnb guide, but if there are any mistakes let me know!

## Why was this MR needed?

Because the entire coffee script codebase was transferred over to ES5 with a plan to move everything over to ES6 😄
