Scala Steward does not update dependencies of `.sc` extensions files

[mvillafuertem]

Hi @fthomas, Why this project do not receive pull request from Steward for .sc extensions files? I have read in the documentation that by default it should be updated

# The extensions of files that should be updated.
# Default: [".scala", ".sbt", ".sbt.shared", ".sc", ".yml", "pom.xml"]
updates.fileExtensions = [".scala", ".sbt", ".sbt.shared", ".sc", ".yml", ".md", ".markdown", ".txt"]

Here my files with extension .sc

Thanks in advance.
