⚙ Adjust future updates

Add these to your `.scala-steward.conf` file to ignore future updates of these dependencies: ``` updates.ignore = [ { groupId = "ch.epfl.scala", artifactId = "sbt-bloop" }, { groupId = "org.scalatest", artifactId = "scalatest" } ] ``` Or, add these to slow down future updates of these dependencies: ``` dependencyOverrides = [ { pullRequests = { frequency = "30 days" }, dependency = { groupId = "ch.epfl.scala", artifactId = "sbt-bloop" } }, { pullRequests = { frequency = "30 days" }, dependency = { groupId = "org.scalatest", artifactId = "scalatest" } } ] ```
