CI: add reporting to the scheduled check

[SMillerDev]

• Have you followed the guidelines for contributing?
• Have you ensured that your commits follow the commit style guide?
• Have you checked that there aren't other open pull requests for the same formula update/change?
• Have you built your formula locally with HOMEBREW_NO_INSTALL_FROM_API=1 brew install --build-from-source <formula>, where <formula> is the name of the formula you're submitting?
• Is your test running fine brew test <formula>, where <formula> is the name of the formula you're submitting?
• Does your build pass brew audit --strict <formula> (after doing HOMEBREW_NO_INSTALL_FROM_API=1 brew install --build-from-source <formula>)? If this is a new formula, does it pass brew audit --new <formula>?

Hopefully, this will give us advanced warning of build issues.

@Homebrew/core how do people feel about posting failures that occur here to an issue that we mark as "good first issue"? It'll allow people to pick up some small maintenance tasks inbetween big updates.

@SMillerDev Seems reasonable to me if they are sufficiently obvious what the errors are.

See #139929, I think I'll turn off the build reporting for now, until I find a good way to skip it when the problem is that it's not supported on that platform.
