bug: trace.enable() no longer works in pandas/dask backends

Something with option registration doesn’t seem quite right, I haven’t dug into why yet:

In [2]: from ibis.backends.pandas import trace as pandas_trace

Maybe these options should be registered as part of backend init?

That seems reasonable. I’ve got a PR up to replace the existing config with pydantic in #3376, I can address this issue as a follow up to that PR.

It works fine in the old version of ibis, so I think it is a regression, but I haven’t had a chance to track down where.
