Manual backport of #25266 because of lockfile conflicts.
- Update all JS dependencies
- Enable stylint
[`media-feature-name-value-no-unknown`](https://stylelint.io/user-guide/rules/media-feature-name-value-no-unknown)
- Make use of new features in webpack and text-expander-element
- Tested Swagger and Mermaid
To explain the `text-expander-element` change: Before this version, the
element added a unavoidable space after emoji completion. Now that
https://github.com/github/text-expander-element/pull/36 is in, we gain
control over this space and I opted to remove it for emoji completion
and retain it for `@` mentions.
