ci: Removed branch testing due to checkout confusion between branch vs tag

- Removed branch testing as it is not required. Point releases will trigger the event due to `tag` push even when it is not from master branch.

- Added version in inputs for testing

- Added missing `inputs` tag

Changelog-None.
