@flotwig
- When link to a header within the same doc, use `urlhash` instead of
`url`.
- When linking to other doc pages, only reference the final document
name, so instead of `guides/references/configuration`, just put
`configuration`

* Add autogenerated changelog

* Write more human readable changeglog

* Add newly closed issue to changelog

* Add new accessibility feature to changelog

* removed docs link feature - after further review I realize this was not part of PR

* guides: add details on environment variables in proxy configuration (#1545)

* guides: add details on environment variables in proxy configuration

* Mostly restructured the content

- Have main section be ‘View, unset, and set env vars’ - with OSes as
sub sections
- Only have 1 line per command line (since our styling doesn’t really
accomodate more than 1 line :(
- Remove comments from command line - we want users to be able to
copy/pasta as much as possible and comments in the command line are
inavlid.
- Add h3 headers for easier linking to sub-sub-sections
