Adjust build definition and CI process

- Remove `versionScheme` (already set by sbt-version-policy)
- Scope `versionPolicyIntention` to projects instead of `ThisBuild`
- Remove `scalaModuleMimaPreviousVersion` (already handled by sbt-version-policy)
- Remove plugin sbt-version-policy (already added by sbt-scala-module)
- Remove invocation of `versionPolicyCheck` (already invoked by `test`)
- Add invocation of `versionCheck` when publishing a release
