Add support for the new Scala 3 nightly repository (#3838)

Gedochao · web-flow · commit 32b11d945ced · 2025-08-29T16:56:40.000Z
* Add support for the new Scala 3 nightly repository

* Don't pass the transitive dependencies of the Scala 3 bridge to Bloop

* Rename `SonatypeUtils` as `RepositoryUtils`

* Retry new Scala 3 nightly tests on the CI &amp; only run them with Bloop while on Windows

* NIT refactor

* Don't unnecessarily re-run Scala 3 nightly tests

* Enable the new Scala 3 nightly repo when a nightly is used as the default Scala version
