Update Gradle wrapper to 7.5

[breskeby]

Gradle 7.5 (snapshot) comes with(at least) two breaking changes in our build.

1. The api of SharedResource#getResourceLock() that we use in StandaloneRestIntegTestTask has changed
2. Checkstyle tasks are not ran as separate process using the Gradle worker API. That is giving us a huge benefit as it allows us multiple checkstyle tasks for the same gradle project can been run in parallel now. However, how this initially work has finally ended up in Gradle master broke :server:precommit as the checkstyleMain and checkstyleTest require more than the default heap. We provided a fix for this to the Gradle team via this PR already: Add memory config to checkstyle gradle/gradle#20198

With the latest 7.5 snapshot we now see issues with our example plugins build:

Hmm, this seems to be only when running in a composite yes? The transforms being in the list are interesting. I'm wondering if something changed there.

[breskeby]

I'm pretty sure something must have changed. I'm reaching out to the gradle team. I've seen this locally once but also noticed that the first listed task actually has been executed correctly. Also you can see from the output that included builds rootProject name is not taken into account. Seems to pay off to test gradle snapshots early, though I initially only wanted to double check the checkstyle improvements.

I think you mean gradle/gradle#20254, yes?

[breskeby]

Yes 🤦🏻‍♂️

This is now also blocked by a regression in artifact transforms: gradle/gradle#20659
