[bug] score-compose init --provisioners flag doesn't document local file option and doesn't support stdin

[astromechza]

the docs currently show

      --provisioners stringArray   Provisioner files to install. May be specified multiple times. Supports:
                                   - HTTP        : http://host/file
                                   - HTTPS       : https://host/file
                                   - Git (SSH)   : git-ssh://git@host/repo.git/file
                                   - Git (HTTPS) : git-https://host/repo.git/file
                                   - OCI         : oci://[registry/][namespace/]repository[:tag|@digest][#file]

But it also supports local file paths as well!

Also it would be very conventient to also support - as stdin so that we can run:

score-compose init --provisioners=- <<EOF
- uri: template://custom-env
  type: environment
  outputs:
    FIZZ: buzz
EOF
