Template checks (#52)

* Added github action to test templates that are getting added/updated

* Update templates to latest sdk to pass new template check

* Added specific setup-go hash for action

* Added bun to the template check action

* Added concurrency check and switched to bun instead of npm

* Switched to using major tags

* Updated action versions

* Make template checks a required github action
