brew doctor output

❯ brew doctor
Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don't worry or file an issue; just ignore this. Thanks!

Warning: The filesystem on /System/Volumes/Data appears to be case-sensitive.
The default macOS filesystem is case-insensitive. Please report any apparent problems.

Warning: You have unlinked kegs in your Cellar.
Leaving kegs unlinked can lead to build-trouble and cause formulae that depend on
those kegs to fail to run properly once built. Run `brew link` on these:
  pycparser
  cffi

Warning: Homebrew's "sbin" was not found in your PATH but you have installed
formulae that put executables in /opt/homebrew/sbin.
Consider setting your PATH for example like so:
  echo 'export PATH="/opt/homebrew/sbin:$PATH"' >> ~/.zshrc

Verification

• My "brew doctor output" above says Your system is ready to brew. and am still able to reproduce my issue.
• I ran brew update twice and am still able to reproduce my issue.
• This issue's title and/or description do not reference a single formula e.g. brew install wget. If they do, open an issue at https://github.com/Homebrew/homebrew-core/issues/new/choose instead.

What were you trying to do (and why)?

Running an automatic script to update casks to their latest versions.

What happened (include all command output)?

❯ brew bump-cask-pr --write-only --version 10.3,28 --no-audit --no-style my-org/tap/my-cask
Error: Cask 'my-cask' definition is invalid: 'url' stanza failed with: Parameter 'using': Expected type T.nilable(Symbol), got type Class with value MyCustomDownloadStrategy
Caller: /opt/homebrew/Library/Homebrew/vendor/bundle/ruby/2.6.0/gems/sorbet-runtime-0.5.10461/lib/types/private/methods/call_validation.rb:113
Definition: /opt/homebrew/Library/Homebrew/cask/url.rb:171

Bisect shows this error started with the enabling of sorbet: #15705

What did you expect to happen?

I believe this is still supported as it's mentioned in the docs: https://docs.brew.sh/Formula-Cookbook#specifying-the-download-strategy-explicitly

Step-by-step reproduction instructions (by running brew commands)

cask "my-cask" do
  version "1.2.3"
  sha256 "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"

  url "https://example.com/my-org/my-cask", using: CustomDownloadStrategy
  name "MyCask"
  app "MyCask.app"
end


- Have example cask ^
- Try to update it with e.g. `brew bump-cask-pr --write-only --version 10.3,28 --no-audit --no-style my-org/tap/my-cask`

[gibfahn]

The undocumented HOMEBREW_NO_SORBET_RUNTIME=1 works around the issue.

Thanks for the quick fix!
