chore: [VIO-3010] Transition from jenkins to Github Actions

[AdamIsrael]

This commit disables builds through Jenkins, in favor of Github Actions.

Prior to merge, the vio-build/branch webhook will need to be disabled.

This also adds a new, untested release workflow. When a new release tag is created, it should run the release job which will, create a pull request to update the synse-server helm chart.
