Code Review

This pull request updates the scala-library dependency from 2.12.20 to 2.12.21. This is a patch update which, according to the release notes, includes a security fix. The change in build.sbt is correct and the update is recommended.

It's worth noting that the pull request description from Scala Steward mentions that the old version 2.12.20 might still be present in a file or context named sbt. This could not be verified with the files available for this review, but it would be prudent to check for any remaining occurrences of the old version string to ensure the dependency is updated consistently throughout the project before merging.
