Homebrew: Fix deprecated depends_on macos string comparison

[muescha]

Describe the bug

Warning: Calling string comparison format for `depends_on macos:` is deprecated! Use `depends_on macos: :catalina` instead.
Please report this issue to the peripheryapp/homebrew-periphery tap (not Homebrew/* repositories), or even better, submit a PR to fix it:
  /opt/homebrew/Library/Taps/peripheryapp/homebrew-periphery/Casks/periphery.rb:8

Reproduction

run any homebrew command - it prints always.

for example:

brew tap-info peripheryapp/periphery
peripheryapp/periphery: Installed
1 cask

I found that periphery is now available without a tap:

https://github.com/Homebrew/homebrew-core/blob/300b9ab51bab0cbaddbcc9c78632689179bb903d/Formula/p/periphery.rb

so you can uninstall the cask and then untap the peripheryapp/periphery tap and then reinstall it
