Bug: Cannot pass piped command into container

[iamkirkbater]

Given a command similar to the following, ocm-container does not correctly handle this:

ocm-container --ocm-url stage -e MYVAR=TEST -- 'env | grep MYVAR'
Error: crun: executable file `env | grep MYVAR` not found in $PATH: No such file or directory: OCI runtime attempted to invoke a command that was not found
Error: exit status 127

If a string is passed as the command - it should be passed as the argument to bash -c.

We then need to validate this continues to work for automatic cluster login (which it might due to the different entrypoint).
