[meshery/meshery-kuma] Prepare workflows for moving from default "write" to default "read" permission

[sangramrath]

Current Behavior

The workflows and the job(s) in them default to 'write' permissions set at the repository. Permissions for the GITHUB_TOKEN is not set individually at the workflow level.

Desired Behavior

Workflows permissions should default to 'read' and GITHUB_TOKEN permissions should be modified in workflow files to use privileged permissions as required.

Implementation
