ci: build wheel only on origin, make sbom test more robust (#4126)

* fixes #4115

This moves the artifact/wheel build into a separate yml file and makes sure it's run only on the main repo (since it needs some info only available there)

Because test_SBOM started failing while I was working on this, I also improved the test_SBOM failure message so it's not trying to show you the diff of the whole log and instead diffs the relevant lines, then made it a bit more robust to data changes by giving a number range for "number of products with CVEs" instead of a specific number.  This should hopefully stop this test from failing a couple of times per year due to data changes, and make it more obvious what's going wrong if it does.
