Test mvn deploy step

[elliotmjackson]

1. mvn release was not provided a branch to checkout on main. This results in the following:

Exception while executing SCM command.: Detecting the current branch failed: fatal: ref HEAD is not a symbolic ref

I have now provided

-DreleaseVersion=${{ github.ref_name }}
-DdevelopmentVersion=${{ github.ref_name }}-SNAPSHOT
-Dtag=${{ github.ref_name }} 

to the release step where ref_name in the github context is:

The short ref name of the branch or tag that triggered the workflow run. This value matches the branch or tag name shown on GitHub. For example, feature-branch-1.

as our trigger is on tag, our example value for ref_name will be v0.6.11

2. for simplicity, i also split out the build & deploy steps into two actions with separate triggers... this removes confusing conditional logic.

3. a bug existed in the python deploy step as a result of it attempting to run in an environment which didnt exist
