chore(docs): Update commands in Consuming.md

- Update docker command to volume in keycloak_data.yaml.
  - Command fails to run if this file isn't present.
- Update otdfctl client-credentials command.
- Created issue opentdf#1785, that came up when testing this documentation.
  - Specifically, when the otdfctl command tries to run it fails due to it looking for the keycloak host instead of localhost.
- Add --rm to bootstrap keycloak command so no hanging container is leftover.
