Same comment as for original PR

Really nice improvement in terms of numbers! Thanks for doing this!

What we are doing in essence (is anyone else will stumble upon this PR) is

• Migrating slowly to 2022.3 editor since 2021.3 will stop being supported in +- October. For now those tests will still run nightly so it's still covered but should start getting less attention
• Running project/package tests on latest and oldest supported editor per each platform is replaced by specifically targeting combinations which should get us the same coverage (worst case all tests still run nightly but won't block PRs). The distribution times got quite high those days so this should help in reducing waiting time on PRs

As for my commits

1. I noticed that we progressed in editor versions so I used this occasion to add 6000.2 to the list of supported editors. Notice that this will only influence nightly/weekly tests and nothing PR related
2. I noticed that in fix: PVP issues related to assemblies, file names, and other non-xml-API related #3444 we removed testproject-tools-integration project but since the Tools PR that aims to move the project there is still pending I re-added it (since your test definition also required it to be present)

This was my bad. I blindly copied the test definitions over from #3543 and completely missed that I'd also copied the tools integration tests. Seeing as we did remove that test project in #3444 yamato was right to be erroring out. Should be good now.
