👷 re-enable publishing to JSR

[cowboyd]

Motivation

Having many modes of installation for lspx on as many systems as possible is a good thing.

Approach

This runs the current GitHub compile / release jobs in parallel with the JSR publication job. That way, we get the benefit of all of them.

Possible Drawbacks or Risks

• this duplicates the versioning logic between the compilation and and the jsr publication
• Adds an installation vector that does require deno to be installed on your system.
• You will need to make sure that if you install from deno that you pass the required runtime security flags. This could change from version to version
