Error message mentions -rewrite but rewrites also requires -source 3.0-migration

[tpolecat]

I am getting messages about code that can be "rewritten automatically under -rewrite", such as the following:

[error] -- Error: /Users/rnorris/Scala/atto/modules/fs2/src/test/scala/atto/fs2/PipesTest.scala:14:86 
[error] 14 |  property("parse1 parses single value correctly") = forAll(Gen.posNum[Int]) { i: Int =>
[error]    |                                                                                      ^
[error]    |           parentheses are required around the parameter of a lambda
[error]    |           This construct can be rewritten automatically under -rewrite.

but adding -rewrite to my scalacOptions in sbt has no effect.

Just tried it and it works with -source 3.0-migration -rewrite.
