Check NVM Version fails if fallback shell is used

[mirekdlugosz]

When nvm_profile is set to path that doesn't contain bash/zsh/csh/tcsh, role will fall back to setting user_shell.command to /etc/bash -ic and fail the first time it is used:

TASK [morgangraphics.ansible_role_nvm : Check NVM Version] *********************
fatal: [default]: FAILED! => {"changed": true, "cmd": "/etc/bash -ic \"nvm --version\"", "delta": "0:00:00.002488", "end": "2022-05-26 12:32:01.105866", "msg": "non-zero return code", "rc": 127, "start": "2022-05-26 12:32:01.103378", "stderr": "/bin/sh: 1: /etc/bash: not found", "stderr_lines": ["/bin/sh: 1: /etc/bash: not found"], "stdout": "", "stdout_lines": []}

I am pretty confident it should have been /bin/bash -ic.

I don't know if any distro ever shipped /etc/bash (most popular, like Ubuntu or Fedora, don't). And even if it did, it was probably some kind of configuration file, not executable.

Good catch - I'll use the default environment variable SHELL as a default instead
