Re-introduce automated Typescript NPM release

This is in addition to the Scala Maven release provided by the previous
commit. This change is only separated out from the previous commit to
show how the 'standard' release.yml has been modified for this dual
Scala & Typescript release workflow.

Note that #229 already
did a lot of the work involved in getting automated NPM releases going,
this is just a refactoring to work better with the
gha-scala-library-release-workflow.
