Make the generated main(String[] args) test class public

[joshlong]

I've noticed an issue when using Devtools, ./gradlew bootTestRun, and Testcontainers (and I'm using Postgres, though I don't know if that matters) where the app either refuses to start (such as in IntelliJ) or refuses to reload new types. the issue seems to go away when I put public on the generated test class with a main(String [] args) method. Ideally, Devtools wouldn't care about a non-public class for the main method, and I've asked about that here

Thanks for reporting this Josh. This was also a discrepancy with the reference documentation.
