Summary by cubic

Updates the build to sbt 1.13.0 (1.x cross target) and 2.0.7 (2.x cross target), and bumps sbt-ci-release to 1.12.1. Previously used sbt 1.12.14 and 2.0.3; this aligns our build and publishing with the latest releases.

• Uses pluginCrossBuild / sbtVersion to select sbt 1.13.0 for Scala 2.12 and sbt 2.0.7 for other targets.
• No plugin logic changes; only version updates in build.sbt, project/build.properties, and project/plugins.sbt.
• Rollout: ensure CI and local builds have JDK 17+ available for sbt 2, and verify sbt-ci-release still has required publishing credentials.

^{Written for commit e760ca6. Summary will update on new commits.}
