Add --certification-component-id as synonym to --certification-project-id

Is your feature request related to a problem? Please describe.

As related in Jira PEC-648, the overall Partner Connect certification process and documentation now calls projects by the new term components.

Preflight still refers to these entities as projects rather than components.

Describe the solution you'd like.

Preflight should add a command-line option --certification-component-id in addition to the existing --certification-project-id.
In addition, Preflight should add an environment variable, PFLT_CERTIFICATION_COMPONENT_ID for the same purpose.

To keep existing automation working properly, the existing --certification-project-id option and PFLT_CERTIFICATION_PROJECT_ID environment variable should continue to be accepted if specified. However, only --certification-component-id should be shown in the help flags list. If that is not possible, then change the description to indicate that --certification-project-id is also accepted.
