🚨 Fix linter warning of type 'name[template]'

This warning:

    name[template]: Jinja templates should only be at the end of 'name'
    setup-ssh.yml:6 Task/Handler: Ensure {{ lookup('env', 'HOME') }}/.ssh/config.d/ dir is present

Reason for that warning is thin.  Using the actual home dir here adds
not much value, so keep it symbolic.
