[bitnami/seaweedfs] Fix OpenShift compatibility issues for S3 + Filer init containers

[MartinWeise]

Description of the change

The _helpers.tpl did not allow for inclusions of resources (e.g. could not be overriden), so a change of the file is necessary to let the init containers of S3 + Filer pods be run on OpenShift clusters.

Benefits

Init containers of S3 and Filer pods now run on OpenShift clusters.

Great, thank you for the hint on fixing the issue. I could successfully rebase the commits. Never did that before :-) please review my changes.

It seems it's needed to rebase from main since there are some undesired changes affecting NGINX Helm chart
