Standardize chart name for OCI artifact

See issue - big-bang/bigbang#1383 (closed)

This renaming will be fully backwards compatible due to the use of the nameOverride value. The goal is to ensure that OCI artifacts are published with a name matching the values key, HR name, etc.

The only observed changes are to:

• helm.sh/chart labels
• some container names which use the chart name as a prefix
• chart label which follow the <chart name>-<chart version> syntax (none are used in any selectors)
