Brew install deno fails: Xcode 15.0 cannot be installed on macOS 12

[htor]

I'm attempting to install deno using brew but the installer fails because it deems my macOS too old. However, I'm able to install deno with curl -fsSL https://deno.land/install.sh | sh just fine. Is there an error in the brew packaging?

~ $ brew install deno
