Change Settings to Edit profile as per UI

Replaces some shorthand words to enforce standard

The notation we use to represent a note is:

```
NOTE: **Note:**
This is a note
```

This is rendered by Nanoc and presented in an alert box in the docs
site. The second `**Note:**` can be redundant, so let's remove it.

The previous URL had two drawbacks:

1. It didn't match what the title was about (`Assignments to DevOps
   Stages and Groups`, and the anchor was `#designated-technical-writers`).
2. It didn't account for the other sections, like development and API
   guidelines.

These unowned docs need future tense scrubbed out of them too!

Add additional none/unassigned metadata to docs

Also Standardize quote usage & replace look-alike PRIVATE-TOKENs

Make sure change codeblock fence languages from text
to plaintext, yml to yaml

The URLs needs hyphens now, so did a find and
replace to add them.

Find and replace sh with shell

This changes any mention of gitlab-ce to gitlab-foss, and any mention of
gitlab-ee to just gitlab.
