SimvueConfiguration Pydantic fails when creating client

[timothy-nunn]

Running the following code on Simvue 1.1.3 produces a traceback:

from simvue.client import Client

client = Client()

During handling of the above exception, another exception occurred:

It appears that simvue.config.parameters.DefaultRunSpecifications is typed to only accept literal strings while simvue.config.user.SimvueConfiguration.fetch accepts mode as optional. Therefore, on line 202, _run_mode = mode or _config_dict["run"].get("mode") which equates to _run_mode = None or None. This None is passed to the DefaultRunSpecifications and fails the literal check.

Fixed with

[server]
url = "https://test.simvue.io"
token = "mytoken"

[run]
mode = "online"

however, this is a work around I believe because only the [server] config is provided by the SImvue website.
