Unable to respect update frequency when version number is stored as a val

[jweng]

We'd like to only update some library every 30 days. For example, AWS has a new build almost every single day and it is quite noisy. We had following configurations but seems Steward is unable to respect the update frequency when version number is stored in a value in build.sbt.

val cdkVersion = "1.204.0"
libraryDependencies ++= Seq(
  "software.amazon.awscdk" % "iam" % cdkVersion
  "software.amazon.awscdk" % "core" % cdkVersion
)

and in .scalafmt.conf:

dependencyOverrides = [
  {
    dependency = { groupId = "software.amazon.awscdk" },
    pullRequests = { frequency = "30 days" }
  }
]

This dependencyOverrides config seems to be working as expected for other case, i.e where version number shows in place right after the artifact id.
