Let's slow down a little on enhancement PRs to give other maintainers
time to give their feedback.

This is mostly self-directed criticism.

Add support for npm 7

Remove `infrakit` from `GITHUB_PRERELEASE_ALLOWLIST` as it's deprecated

Allow python@3.9 to be non-keg-only

shared_audits: add nuclear to GITHUB_PRERELEASE_ALLOWLIST

Remove IRC mention from README.md

Add more license symbol functionality

Convert forbidden licenses to a string before duplicating to have empty
strings instead of `nil`.

bintray: warn on upload error on uploads

Previously this would only warn on errors for certain Bintray API
requests like publishing. This should now also warn on error for curl
POST uploads (if the appropriate flag has been passed).

docs/vale-styles: Bump all style violations to "error" level so they fail CI

- I don't necessarily agree with this, but it's AP style that words with
  four or more letters should start with a capital when in titles.

- I added these all the way back in December 2019 in #6826, but only
  today realised that things have been failing unnoticeably because
  "warning" level exits with status code 0, so doesn't fail CI.
- Upgrading to "error" level will enable us to see the style errors in
  our docs and fix them faster.
- My editor also auto-formatted the YAML to have double quotes instead
  of single.

- Otherwise this surfaces an error and suggests a fix that doesn't match
  Apple's branding.
