Additional context

[danny-smit]

There is a chicken and egg problem with the tests. The tests for this pull request were failing due to the issue fixed with pull request #288. The tests of pull request #288 were failing due to the problems fixed by this pull request.

Therefore I've pulled in the commit made by @Lucianovici to see if the tests succeed with the fixes of both of the pull requests. I can remove the commit again if it is cleaner to merge both pull requests separately.

Root cause is saltstack/salt#60188
Maybe there is no need to change all salt formulas, let's see how Saltstack team handles this.

Thanks for pointing out the other issues. I agree, it seems better to wait for a response from Salt devs before including the fix for the 'imports'.

I'll remove that commit from this pull request again, since we already have #288 for that.

For the record, the tests succeeded with the commit from #288:

Thanks @danny-smit, merging this based on that outcome. With the actual testing being here in GitHub Actions, the failures won't prevent semantic-release from running -- which has actually completed as I'm typing this!

Appreciate the review, @noelmcloughlin.
