Disabled SelectorFormat rule for SCSS Lint in order to get the Rake
task passing sooner.

SelectorFormat enforces that CSS classes and IDs use lowercase
hyphenated style, `like-this`, but a not-insignificant amount of
selectors in the codebase are `like_this`.

Fixing the selectors that break this rule would require changing HTML
as well, and potentially break JavaScript hooks, among other things. So
I decided to disable this rule for the time being, hopefully making it
easier to fix all the remaining warnings SCSS Lint is giving by removing
the most problematic rule.

Discussed in #14299.

Reload the schema before restoring a database backup

If a user tries to downgrade and restore after a failed upgrade,
the database may still contain newer tables. Reload the older
schema before restoring the database to avoid future upgrade
problems. Also, add a rake task to help users add migration
versions to the database so it's easier to recover from these
errors if they do occur. Fixes #13419

CI: Add 'triggers' keyword to 'only' and 'except' lists to allow control over when triggers cause builds to run

Currently, the `only` and `except` keywords in `.gitlab-ci.yml` only accept ref names or the special `branches` and `tags` keywords. However, these are primarily useful when controlling how repository activity affects the creation of builds. In my case, instead of building on every commit, I'd like to use the following logic:

- If the repository is tagged, do a build.
- Any other normal commits should not cause a build.
- If a build is triggered via the API, always create one for the specified ref.

From what I can tell, this isn't possible via the existing YAML syntax. In this MR, I introduce a new keyword `triggers` that goes along with `branches` and `tags`. I can implement the logic above using the following job configuration:

```yaml
only:
  - tags
  - triggers
```

I updated the tests and documentation to reflect this and everything seems to pass.
