Added profile to pom for creation of unshaded Rascal jar

[rodinaarssen]

Since the recent addition of several maven dependencies, rascal-maven-plugin no longer works due to multiple dependency injection errors. This PR adds a maven profile for rascal that produces an unshaded jar/pom, which removes unintended dependency injection.

[DavyLandman]

LGTM, although we should also add it to our build.yaml file, so that we do a deploy of the regular and one for the -P unshaded version?
