[teraslice-chart] Add Teraslice Helm Chart Release Workflow

[sotojn]

This PR makes the following changes:

• Adds initial release workflow for the Teraslice chart.
  • This workflow will check ghcr for the listed version in the Chart.yaml to see if a tag already exists
    • If it exists, it will stop and move on to building docs
    • If not, ci will package the new chart in a tarball file and update the index.yaml file with the change and commit the change to the index.yaml to the master branch. It will then upload the tarball as an OCI artifact to the terascope gitHub container registry.
  • In both scenarios it will generate an index.html file and append these files in the /charts directory of the documentation build static files.
  • These actions are triggered on every merge to the master branch
• Updates the charts default values to use the latest teraslice version and node version
