Suggest maven-compiler-plugin 3.11.0 in docs

I found that with 3.10.1, Error Prone (and NullAway) warnings aren't even printed (!).  Some related discussion at uber/NullAway#830.  I created a relevant sample repo:

https://github.com/msridhar/ep-maven-test-warnings

You can compare running `mvn clean compile` as is with changing [this line](https://github.com/msridhar/ep-maven-test-warnings/blob/main/pom.xml#L23) to be `3.10.1`; with the latter version many fewer warnings are printed, and no Error Prone warnings are printed as far as I can see.

I'm open to adding text that warns users off of versions earlier than 3.11.0 if we think that is warranted.

Fixes #4162
