[Homebrew] Cask fails to install: `depends_on macos: :catalina` is disabled

OmniGet version
0.9.0
Operating system
macOS (Apple Silicon)
Platform / site that failed
Homebrew (cask tonhowtf/tap/omniget)
Steps to reproduce
brew install --cask tonhowtf/tap/omniget- Homebrew taps the repo, then errors out before downloading anything.
- Reproduced on a clean Homebrew setup - no other taps involved.
Expected behavior
The cask should install on macOS 27 (Apple Silicon). The app itself runs fine on current macOS - the only blocker is the cask metadata (depends_on macos: :catalina was disabled by Homebrew with no replacement).
Deleting that single line fixes the install. Full report with the fix: tonhowtf/homebrew-tap#3
