Use defined colour for a language when available

## What does this MR do?

This MR changes the colours of the different languages in the language graph.  It now uses the colour set in Linguist instead of the first six characters of the SHA256'd language name where possible.  If Linguist has no colour defined for a given language, it falls back to the old method of finding a colour.

I talked with @connorshea about creating this MR [on Twitter](https://twitter.com/connorjshea/status/784390886222286849) a few hours earlier. Here's also an older [tweet from May](https://twitter.com/nilsding/status/737018807223496708) where we discussed some possible improvements to the graph. 

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

Hopefully none ;)

## Why was this MR needed?

Aesthetics.

Use forked github-markup gem to enable python3 support with omnibus

## What does this MR do?
Changes the version of `github-markup` gem we are using, to be the forked one with the changes to enable python3 support.
The change is backward compatible with users using Python 2, and will only be running with Python 3 in Omnibus (with the help of a custom patch we apply there).

## Are there points in the code the reviewer needs to double check?
Make sure backward compatibility isn't broken for source installs.

## For the release manager

You need to make sure you pickup into stable this merge request as well (for omnibus): https://gitlab.com/gitlab-org/omnibus-gitlab/merge_requests/1015 as it's part of the fix, otherwise package will fail to build.

## Why was this MR needed?
We had some regressions with .rst rendering that were fixed, but still some issues with encoding persisted (this MR will fix that). See: https://gitlab.com/gitlab-org/gitlab-ce/issues/21696

Keep a copy of gems needed by our releases as CI artifacts

This is meant as insurance in case a gem GitLab needs is ever removed
from rubygems.org. After we merge this, all future GitLab tags will
have a CI artifact archive containing all the gems (for all platforms)
specified in Gemfile.lock for that revision.

Only runs on tags (so we don't constantly create 50MB gem cache bundles).

Ensure that whitespace doesn't cause adding members to fail

I recently had to debug an issue where adding users wasn't working. It turned out that I was hitting "space" to confirm a `select2` dialog, and the server would throw out the whole email address because it was invalid. It looked as though GitLab was entirely ignoring my add-member request.

Here's a fun gif:
![out](/uploads/5c306addb764067bca54add3b7a53c6c/out.gif)

Ideally, there should also be validation client-side, so that the server doesn't need to silently fail, and the user will know what's going wrong. I'll look into creating an issue for that.

Additionally, GitLab already seems to trim email addresses, sometimes? If you add _two_ address, with spaces, then the `value` of the `user_ids` DOM element will have the first `n-1` addresses without spaces. Weird.

**TL;DR: Now spaces are always trimmed from new-member email addresses.**
