Missing JobItem FinishCode

[fenimore]

Describe the bug
The class FinishCode is defined without all the finish codes tableau cloud will send:
https://github.com/tableau/server-client-python/blob/master/tableauserverclient/models/job_item.py#L76

    class FinishCode:
        """
        Status codes as documented on
        https://help.tableau.com/current/api/rest_api/en-us/REST/rest_api_ref_jobs_tasks_and_schedules.htm#query_job
        """

        Success: int = 0
        Failed: int = 1
        Cancelled: int = 2

In the documentation linked in the docstring it writes that for Bridge Jobs:

For bridge extract refresh jobs, a finishCode of 0 indicates that the bridge client is assigned to execute the job, while a 3 indicates that the job completed.

I can confirm that sometimes a bridge extract will send a 3

I don't know if it's as simple as adding Completed: int = 3 to the class or if there are more parts of the client you want to adjust

Versions
Details of your environment, including:

• Tableau Cloud
• Python version: 3.10
• TSC library version (latest)

To Reproduce
Launch a cloud bridge job

Results
We'd expect the finish codes to align with what the API sends us

The missing FinishCode is causing issues for me as well. Is there an ETA on when this PR will be merged?
