MLE-12345 Merging master into dev and bumping to 8.0-SNAPSHOT

Minor CVE thing. Getting rid of the PR template as well as it's not needed and GitKraken keeps trying to use it.

MLE-24717 Bumping logback to 1.5.19

Removed hack in BitemporalTest for bug that is fixed. And bumped mockito, realized it can go to 5 safely now.

Bug was fixed in the server.

Don't know why this didn't cause a failure initially, but did cause failures in nightly regressions.

Also bumped an old version of xmlunit. Pretty sure the junit:junit stuff can be easily removed next.

Unfortunately can't upgrade to JUnit5 in ml-development-tools, far too many breaking changes to fix for now.

Having issues on Jenkins, just want to get dynamic stages in place for now.

Wanted to move this into a separate class so it's easier / cleaner to prototype an incremental check listener. Also made BatchWriteSet nicer by making a bunch of fields final. No change in functionality, just cleaning up code.

Was going crazy trying to figure out if a "writeSet" was a BatchWriteSet or DocumentWriteSet. Now using more explicit names.

Should have renamed this in a prior release.

Info-level was too verbose for token generation. Also fixed a little bug in an error message built for an exception.
