AbhishekJ 27520d3a15 Refactor stx-node-metrics-expo**-helm package name
Previous changes enabled the auto-versioning of helm charts to ensure
FluxCD helm controller recognizes chart changes. As a result
of this refactor, the package name
`stx-node-interface-metrics-exporter-helm` became outdated.
This commit updates its name to
`stx-node-interface-metrics-exporter`. It also improves chart
versioning based on the Debian environment.

Story: 2010929
Task: 50072

Test Plan:
PASS: Build all packages generating an application tarball and
      check whether the charts' versions are correct.
PASS: Validate basic application lifecycle operations:
      upload/apply/remove/delete.

Depends-On: https://review.opendev.org/c/starlingx/app-node-interface-metrics-exporter/+/916894
