fix(release): move github release creation to git tasks

[fahslaj]

Current Behavior

nx release fails when configured to create a github release because the release is created before changes are committed and tagged. This results in duplicate git tags being created and an error.

Expected Behavior

nx release properly creates a github release after committing, tagging, and pushing changes. nx release changelog is unaffected.

The programmatic API example docs need to updated to no longer treat the return value of releaseChangelog as a status code, and @juristr will need to update his recent blog post once this is released
