invenio-cli check-requirements --development fails on non-RDM site

[mesemus]

Package version (if known): 1.0.17

Describe the bug

invenio-cli in version 1.0.17 started checking for RDM version - see https://github.com/inveniosoftware/invenio-cli/blob/master/invenio_cli/commands/requirements.py#L195

The problem is that if Invenio-cli is used on site without invenio-app-rdm installed, this check fails with a key error:

Traceback (most recent call last):
  File "/private/tmp/blah/.venv/invenio-cli/bin/invenio-cli", line 8, in <module>
    sys.exit(invenio_cli())

    r"[0-9]*\.[0-9]*\.[0-9]*", parsed.data["default"]["invenio-app-rdm"]["version"]
KeyError: 'invenio-app-rdm'

There is currently no workaround for this.

Steps to Reproduce

1. Install invenio with invenio-cli
2. Remove invenio-app-rdm from the pipfile
3. Run check-requirements

Expected behavior

The check is supposed to pass, ideally allowing to use node 16
