[FEATURE] Change release workflow to be scheduled fortnightly

[agdimech]

Describe the feature

Change release workflow to be scheduled fortnightly in order to throttle the number of releases.

Use Case

PYPI has limitations on the Project size and as such we need to throttle our releases.

Proposed Solution

• Change the release script to be scheduled.
• Add a check to ensure latest commit has a tag (meaning it has been released), otherwise abort.
• Manual releases will still be supported.
