Include wrapper configs in buildscript

[Kichura]

From the updated source code:

// HACK: Gradle overwrites all customized wrapper configurations,
// Meaning we have to include them in buildscript to make them persistent.
// (Source: https://github.com/gradle/gradle/issues/36172)

I have the same opinion as RK here. I would only override default values if we actually have situations or reproducable steps where changing them helps, especially when it gets hacky. Same rules apply for GH actions from now on, as I want to keep configurations as small as possible.
