Describe the bug

I am able to successfully create auth2 clients using Ory REST API by setting these two lifespan fields for OAuth2 clients:

"client_credentials_grant_access_token_lifespan": "720h",
"jwt_bearer_grant_access_token_lifespan": "720h",

I am able to fetch the client using the REST endpoint, it returns these two values as:

    "client_credentials_grant_access_token_lifespan": "720h0m0s",
    "jwt_bearer_grant_access_token_lifespan": "720h0m0s",

But it throws exception when I try to create or list existing Oauth2 clients using Python SDK:

ValidationError: 2 validation errors for OAuth2Client
client_credentials_grant_access_token_lifespan
  Value error, must validate the regular expression /^[0-9]+(ns|us|ms|s|m|h)$/ [type=value_error, input_value='720h0m0s', input_type=str]
    For further information visit https://errors.pydantic.dev/2.9/v/value_error
jwt_bearer_grant_access_token_lifespan
  Value error, must validate the regular expression /^[0-9]+(ns|us|ms|s|m|h)$/ [type=value_error, input_value='720h0m0s', input_type=str]
    For further information visit https://errors.pydantic.dev/2.9/v/value_error

Reproducing the bug

1. Create M2M Client with OAuth2Client as:

ory_client.OAuth2Client(
        client_name=client_name,
        grant_types=["client_credentials"],
        response_types=["token"],
        access_token_strategy="jwt",
        skip_consent=True,
        audience=["dev-audience"],
        scope="read:all",
        token_endpoint_auth_method="client_secret_post",
        token_endpoint_auth_signing_alg="RS256",
        jwt_bearer_grant_access_token_lifespan="720h",
        client_credentials_grant_access_token_lifespan="720h",
    )
    
    api_response = api_instance.create_o_auth2_client(m2m_client)

Relevant log output

Exception when calling OAuth2Api->list_o_auth2_clients: 2 validation errors for OAuth2Client
client_credentials_grant_access_token_lifespan
  Value error, must validate the regular expression /^[0-9]+(ns|us|ms|s|m|h)$/ [type=value_error, input_value='720h0m0s', input_type=str]
    For further information visit https://errors.pydantic.dev/2.9/v/value_error

Additional Context

No response

Start with the Python SDK's OAuth2Client model and its validation for client_credentials_grant_access_token_lifespan and jwt_bearer_grant_access_token_lifespan. Reproduce the issue with list_o_auth2_clients and the shown 720h configuration, then verify that the REST response value 720h0m0s is accepted without validation errors.
