cacert deployment scope fix

General MR

Summary

.Values.configuration.backupStorageLocation[*].caCert was not able to be set to a value. This would cause the following error:

% kubectl get hr velero -n bigbang
NAME     AGE   READY   STATUS
velero   37m   False   Helm upgrade failed for release velero/velero-velero with chart velero@5.2.2-bb.0: template: velero/templates/deployment.yaml:293:27: executing "velero/templates/deployment.yaml" at <include "velero.secretName" .>: error calling include: template: velero/templates/_helpers.tpl:49:14: executing "velero.secretName" at <.Values.credentials.existingSecret>: nil pointer evaluating interface {}.credentials

This prevented interaction with any S3 source that requires caCert to validate connection.

The issue is caused when the deployment attempts to add a cacert volume, which calls out to {{ include "velero.secretName" . }}, which attempts to use the .Values.credentials key-map. This would normally not be an issue, but around Velero chart 4.0.3-bb.0 we changed backupStorageLocation to a map and and everything got a bit out of wack.

There are a decent few places that this is occurring
