Instruction

1. Find generateScalaDocumentation task in Build.scala
2. Find generateDocumentation call inside task definition
3. Add the part of documentation that you want to fix to snippet compiler setting (You can find usage here)
4. Path to scala3 library is stored in dottyLibRoot variable
5. E.g. if you want to run snippet compiler on scala.quoted, add $dottyLibRoot/scala/quoted=compile
6. If you want to run snippet compiler on docs/contributing, add docs/docs/contributing=compile
7. Fix all failing snippets or override snippet compiler flag if it's necessary.
8. You can override flag by adding sc:flag after "```scala" in snippet.
9. You can hide piece of code by doing:

//{
def someHiddenCode = ???
//}

10. Create PR to master.
