Fix for picking the right helm chart version during release cut (#8196)

# Description

To find the correct helm chart version in our code, we search for the
release major value but wildcard the patch value. We need to update the
versioning logic during the Helm install to handle a few different
cases:
1. If there is a pre-release version (i.e. -rc1, -rc2, etc), we want to
find a helm chart version that is an exact match
2. If there is a full release version, we want to find a helm chart
version that matches the release value but wildcards the patch value (in
case we have a patch release)
3. For dev builds, the release version will always be `0.42.42-dev` so
this value should be hardcoded as the version.
