Remove HTTPS workaround added in #6673

[mbien]

The problem will likely resolve itself (due to updates in tested gradle versions or other means), once it is working again, remove the workaround added in #6673

See first //TODO in MicronautGradleArtifactsImplTest and ProjectViewTest (c0f09c9)

found

System.setProperty("javax.net.debug", "ssl:handshake");

to be useful for SSL debugging. But it produces a lot of output with is mixed with the test output which is also a lot. Would be interesting to diff the two https handshake logs of the gradle Downloader with and without the workaround.

sorry about the noise, I ran the wrong tests and got excited too fast.

higher priority than this would be to get gradle tests testable on 21+, since they are locked to JDK 17 atm. I still hope that things like this resolve themself via dependency updates.

Once the latest wrappers+gradle is used we can take another look. Also tracked via #7871
