Update build.gradle to support Gradle 7+

[samermurad]

Except the installArchives task, which I really don't know how to handle, these values work; the plugin part is a pretty simple change. I don't know how to fix the publication part though, I could try to fix it if you give me a general direction on where to look..

@maxkomarychev Is it possible for you to take a look at this PR and the question posted? It seems that this repo needs this fix for the Gradle 7+.

Any idea when this will be merged in/released? I've tested this update and all seems to work fine.

@maxkomarychev could you review and merge it please?

[tr3v3r]

@maxkomarychev same here! Could please review and merge?)

I've improved on this PR in a patch with patch-package, this fixes the issue with publication to maven
