Add Scala 3 support

[SethTisue]

would a volunteer like to attempt this? it would be helpful even just to have a failing draft PR that shows where the next roadblock is, and then we could chip away it from there

I published ssl-config and cachecontrol today for Scala 3, so that helps

#590 should be merged before any attempt is made at this

@SethTisue As you probably have noticed, #590 got merged.

@xuwei-k Do you can/want to help?

Could not compile play-ws with Scala 3 due to https://github.com/lampepfl/dotty/issues/12731 😢

I thought this was very clever of me at the time (it was mostly actually Adriaan)

@xuwei-k @SethTisue did you see these 2 comments? Replacing F-bounds by intersection types? WDYT? Also see https://github.com/lampepfl/dotty/issues/13133 and https://github.com/lampepfl/dotty/issues/10638#issuecomment-739151145

If you have an F-bounded type T <: F[T] simply replace it with T. Then everywhere T is used, replace it with T & F[T].

@mkurz I'm sorry but I don't know what to think about that, and I don't feel that have time to dig into it. :-/

[mkurz]

@SethTisue Currently not so much time as well (coming weeks)...

Was implemented in #604 but has some comments https://github.com/playframework/play-ws/pull/604#pullrequestreview-906492465 from @mkurz
