fix to reduce Kubernetes local schema size

[AlexFenlon]

Proposed changes

The Helm secret file size exceeds it limits. This is fixed by removing unused files in the Kubernetes local schema folder.
This fix solves this.

The only required file is _definitions.json, the rest are not required and are taking up too much space for helm to compress.

Updated the automated workflow to reflect these changes
