GoReleaser's Homebrew template always emits a bare `depends_on :macos`
for macOS-only formulae. Combining that with the `depends_on :macos =>
:ventura` line injected via custom_block triggers a Homebrew deprecation
warning on `brew upgrade`:
Warning: Calling `depends_on :macos` with `depends_on macos:` is deprecated! Use `depends_on :macos` with `depends_on macos:` inside an `on_macos` block instead.
Please report this issue to the cirruslabs/homebrew-cli tap (not Homebrew/* repositories), or even better, submit a PR to fix it:
/opt/homebrew/Library/Taps/cirruslabs/homebrew-cli/tart.rb:22
Declaring the version constraint inside an `on_macos` block is the form
Homebrew recommends and silences the warning without changing behavior
(still macOS-only, Ventura or newer).
