buildSrc setup instructions

[aSemy]

Describe your use-case which is not covered by existing documentation.

Hey! I'd like to try this out, but on a smaller scale, just in a single project's convention plugins.

It'd be handy to have instructions for setting up gratatouille in buildSrc, since that's a very lightweight way of configuring plugins.

Reference any relevant documentation, other materials or issues/pull requests that can be used for inspiration.

By using two different modules, Gratatouille ensures that Gradle classes do not leak in your plugin implementation and vice-versa.

It's a bit heavy to create two subprojects if I just want to use Grata for a single task. Could creating separate feature variants help instead? Then a single subproject could have independent source sets. https://docs.gradle.org/current/userguide/feature_variants.html

Are you interested in contributing to the documentation?

Yes. How about we set up a full site? I really like using Docusaurus!

Hey thanks for opening this!
That's definitely something that has been at the back of my mind for a while (see also #4). Thanks for the nudge, I'll look into what can be done here.

Re: documentation, I've been toying with Writerside lately. Never used Docusaurus but definitely in to try it out!

Non-isolated mode is available in version 0.0.4: #13. Let me know what you think (I updated the README to make classloader isolation optional)
