Remark42: init container command improvement (#1249)

* Remark42: init container command improvement

This patch makes the command from the init container configurable.
It does not modify the previous behavior since it has been copy pasted
in the values.yaml file.
You can change initCommand and initArgs to change the default behavior.

Fixes #1248

* Updated chart version and documentation
