Fix/bootstrap m2 directory (#389)

* Updates CI so that it only builds and publishes a docker container
image if the commit has a git tag that starts with `v`, such as
`v0.5.2`.
* Updates the docker container build so that it pre-populates the
contents of the `/root/.m2` directory with the dependencies that are
needed the first time that the plugins
`org.cyclonedx:cyclonedx-maven-plugin:makeAggregateBom` and
`com.corgibytes:versions-maven-plugin:resolve-ranges-historical` are
run. This fixes #388.
