This feature needs to be documented, so here is the documentation

Embed metrics charts in issues

See merge request gitlab-org/gitlab-ce!29691

See https://gitlab.com/gitlab-org/gitlab-ce/issues/30423

Order projects by name in the "Move issue" dropdown

See merge request gitlab-org/gitlab-ce!30778

This pagination is not used anywhere so there is no reason
to keep it. It seems the usage of offset_id was probably
removed in 90c60138

Fix syntax error in script

See merge request gitlab-org/gitlab-ce!30994

Markdown issues: Checkbox inside blockquote status won't be saved

See merge request gitlab-org/gitlab-ce!30952

Resolve "OAuth2 support with GitLab personal access token"

See merge request gitlab-org/gitlab-ce!30277

PATs are accepted using the OAuth2 compliant header
"Authorization: Bearer {token}" in order to allow for
OAuth requests while 2FA is enabled.

Fix unordered list spacing (part 2)

See merge request gitlab-org/gitlab-ce!30796

Correct the spacing of unordered markdown lists
in docs, to maintain standards of documentation,
in /user and others.

Standardize page objects use on CE Plan tests

See merge request gitlab-org/gitlab-ce!30962

Wiki Usage Ping for Create SMAU

See merge request gitlab-org/gitlab-ce!30864

This adds a counter to count page creation, which is reflected in the
usage-data we collect.

The number created is stored in Redis, avoiding DB access.

The leading slash will cause some not friendly command line behavier,
for example:

vim:
```
~/gitlab-ce/changelogs/unreleased $ vim -30974-issue-search-by-number.yml
VIM - Vi IMproved 7.4 (2013 Aug 10, compiled Jun 07 2019 15:35:43)
Unknown option argument: "-30974-issue-search-by-number.yml"
More info with: "vim -h"
```

git:
```
~/gitlab-ce/changelogs/unreleased $ git add -30974-issue-search-by-number.yml
error: unknown switch `3'
usage: git add [<options>] [--] <pathspec>...

    -n, --dry-run         dry run
    -v, --verbose         be verbose

    -i, --interactive     interactive picking
    -p, --patch           select hunks interactively
    -e, --edit            edit current diff and apply
    -f, --force           allow adding otherwise ignored files
    -u, --update          update tracked files
    -N, --intent-to-add   record only the fact that the path will be added later
    -A, --all             add changes from all tracked and untracked files
    --ignore-removal      ignore paths removed in the working tree (same as --no-all)
    --refresh             don't add, only refresh the index
    --ignore-errors       just skip files which cannot be added because of errors
    --ignore-missing      check if - even missing - files are ignored in dry run
```

There's no other unreleased changelog has a filename with leading slash,
so I think this one should be corrected.
