Bump Gradle to version 7.6

[glefloch]

This bumps gradle to 7.6 with java 19 support !

It could just be flaky tests but there are a lot more Gradle tests failing than usual. Probably worth a look.

Rebasing to trigger a new CI run.

Really, the fact that we have some flaky tests in the Gradle testsuite doesn't help to take an educated decision.

There seem to be metaspace and heap issues.

We should probably wait for gradle/gradle#23215 to be fixed (currently assigned to 7.6.1)

[gastaldi]

Let's wait if that is fixed in 7.6.1. Closing this now
