Scala.js >1.18

[bpholt]

This repo pins Scala.js to 1.18:

steward/.github/.scala-steward.conf

Line 4 in 8693840

{ groupId = "org.scala-js", artifactId="sbt-scalajs", version = "1.18." }

Some of the PRs that this instance creates are now failing because they require Scala.js 1.20.1 (e.g. typelevel/log4cats-natchez#160). Can this be unpinned or updated? I'm not sure why it was originally pinned.
