Datacatalog.get_source_time_range() will error if the source does not have a time dimension

HydroMT version checks

• [X] I have checked that this issue has not already been reported.
• [X] I have checked that this bug exists on the latest version of HydroMT.

Reproducible Example

Using deltares data catalog:

datacatalog.get_source_time_range("gcn250")

Current behaviour

Will result in a key error because ds.raster.time_dim is None in ds[ds.raster.time_dim].min().values

Desired behaviour

If the source does not have a time dimension it should give back a warning. I suggest to raise a TypeError when ds.raster.time_dim is None in detect_time_range() in the rasterdataset adapter.

Additional context

No response

indeed definitely good to have a better error. This might also be a nice place for the new NoDataStrategy pattern so we give users flexibility in this.
