* feat(manager): share OCI Helm chart resolution across managers
Add getOciChartDep() to helmv3/oci.ts and use it in argocd, fleet, flux,
helmfile, helmsman, helmv3, kustomize, sveltos, terraform and vendir.
- set pinDigests: false for OCI charts in all of them
- apply registryAliases to OCI charts in argocd, helmfile and helmsman
- keep the registry port in terraform helm_release repositories
- skip fleet OCI charts without a version instead of using 'undefined'
* docs(manager/helmv3): correct the OCI chart pinDigests rationale
* refactor(manager/helmfile): drop redundant OCI repository url guard
The repository schema already requires url to be a string, so the falsy
branch could not be reached by parsed input and left the patch partially
covered.
* test(manager): replace file snapshots with explicit assertions
* test(manager): replace inline snapshots with explicit assertions
* test(manager): assert on relevant sections instead of full bodies
* test(manager): drop assertions implied by full equality
* test(manager): address review feedback
* test(manager): assert depType and versioning in the regex matcher
Renames `lookupName` to be `packageName`.
BREAKING CHANGE: Use `packageName` instead of `lookupName` if interacting with Renovate datasources directly.
Moves datasource, manager, platform and versioning code from lib/ into new lib/modules/
