[Geod24]

macOS-12 is about to be EOL and is already starting to throw warnings in Homebrew, so upgrade it to 13 before the deadline which should be in the next couple months.

seems to fail, though

[Geod24]

There's a few errors, some of them probably irrelevant. However this caught my eye:

1c1
< -version=someVerIdent -version=Have_describe_project -version=Have_describe_dependency_1 -version=Have_describe_dependency_2 -version=Have_describe_dependency_3 -version=anotherVerIdent
---
> -version=someVerIdent -version=Have_describe_project -version=Have_describe_dependency_1 -version=Have_describe_dependency_2 -version=Have_describe_dependency_3 -version=anotherVerIdent 
\ No newline at end of file
Error:  /Users/runner/work/dub/dub/test/4-describe-data-3-zero-delim.sh:111 The null-delimited dmd-style --data=versions did not match the expected output!

I don't know whether that's a change in diff or shell behavior. Anyone has a machine to test ?
