Dotty build

[cquiroz]

Though it seems dotty can run using withDottyCompatibility. it would be nice to get a dotty build of this lib

[sjrd]

I do not intend to do so. IMO, all libraries should either publish for 2.13, or for 3. Until further notice, I intend to publish for 2.13, and let Scala 3 users depend on it with withDottyCompat.

See scala/scala3#10244 for background.

FWIW, I've confirmed this works fine in minitest, but only because we don't depend on the macros.

I think we should publish Scala 3 build, at least for Scala Native.
doesn't seem to work with Scala Native, because it brings dependencies on libraries (on Maven Central):

sbt> portable-scala-reflectNative/libraryDependencies
[info] * org.scala-lang:scala-library:2.12.13
[info] * org.scala-native:nativelib:0.4.0
[info] * org.scala-native:javalib:0.4.0

[info] * org.scala-native:junit-runtime:0.4.0:test
[info] * org.scala-native:junit-plugin:0.4.0:plugin->default(compile)

The .cross(CrossVersion.for3Use2_13) trick then causes this when attempting to use Scala Native with Scala 3:

[error] Modules were resolved with conflicting cross-version suffixes in ProjectRef(uri("file:/home/ondra/Projects/sbt-locales/"), "apiNative"):

Example of such behavior can be seen in this PR cquiroz/sbt-locales#190
