Current Behavior

Helm charts are produced with coder_helm_.tgz

This doesn't align with the standard helm package command and is causes issues when uploading the charts to a nexus instance where by nexus generates the index.yaml off the helm package output but uploads the artefact as "coder_helm_.tgz"
Ticket would be to update the coder release pipeline such that the resultant artefact aligns with helm naming conventions.
