Setting a Double field using a Int doesn't work in Scala3

[adamw]

To reproduce:

case class X(a: Double)
X(0).modify(_.a).setTo(1)

Hmmm, this might be impossible to solve on quicklens side, since this seems to be a change (or bug) in type inference. Scala 3 ifers [X, AnyVal], when Scala 2 inferred [X, Double]
