Add additional Run Sources to runs model.

[gatesy666]

Use-cases

When listing runs in an organisation client.runs.list_for_organization(args.organization, org_options) will fail with the following pedantic error:

pydantic_core._pydantic_core.ValidationError: 1 validation error for Run
source
  Input should be 'tfe-api', 'tfe-configuration-version', 'tfe-ui' or 'terraform+cloud' [type=enum, input_value='terraform', input_type=str]
    For further information visit https://errors.pydantic.dev/2.12/v/enum

This will also occur when runs have a source of:

tfe-run-trigger
tfe-infrastructure-lifecycle

Attempted Solutions

To allow runs.list_for_organization to successfully retrieve all runs; adding the following to class RunSource(str, Enum) in models/run.py has worked for me:

Run_Source_Terraform = "terraform"
Run_Source_Run_Trigger = "tfe-run-trigger"
Run_Source_Infra_Lifecycle = "tfe-infrastructure-lifecycle"

Proposal

Could all possible run sources for a run be added to the RunSource model.

class RunSource(str, Enum):
    """RunSource represents a source type of a run."""

    Run_Source_API = "tfe-api"
    Run_Source_Configuration_Version = "tfe-configuration-version"
    Run_Source_UI = "tfe-ui"
    Run_Source_Terraform_Cloud = "terraform+cloud"
    Run_Source_Terraform = "terraform"
    Run_Source_Run_Trigger = "tfe-run-trigger"
    Run_Source_Infra_Lifecycle = "tfe-infrastructure-lifecycle"
    # Add any other possible sources...
