Triggering tag deployment from CI to Lagoon fails the job

[AlexSkrypnyk]

[INFO] Started deployment.
[INFO] Started LAGOON deployment.
[FAIL] Missing required value for DREVOPS_DEPLOY_BRANCH or DREVOPS_DEPLOY_PR.

Exited with code exit status 1

Need to assess how this should work with Lagoon: either do nothing and success the build with a message OR create a custom branch as deployment/[tag] and deploy OR make this an option

[AlexSkrypnyk]

Tag-based deployments are not supported

uselagoon/lagoon#133

But still need to fix the failure in CI
