Adjust future updates

Add this to your .scala-steward.conf file to ignore future updates of this dependency:

updates.ignore = [ { groupId = "io.github.cquiroz", artifactId = "scala-java-locales" } ]

Or, add this to slow down future updates of this dependency:

dependencyOverrides = [{
  pullRequests = { frequency = "@monthly" },
  dependency = { groupId = "io.github.cquiroz", artifactId = "scala-java-locales" }
}]
