Adjust build definition and CI process

- remove `versionScheme` (already set by sbt-version-policy)
- scope `versionPolicyIntention` to projects, instead of to `ThisBuild`
- replace `versionPolicyDependencySchemes` with `libraryDependencySchemes`
- remove `scalaModuleMimaPreviousVersion` (already set by sbt-version-policy)
- remove invocation of `versionPolicyCheck` from CI (already invoked by `test`)
- add invocation of `versionCheck` before publishing a release
