Error Description

I am using HMA and providing the new, streamlined Metadata object for it. If I try to customize the synthesizer (eg. by setting distributions for individual columns), then HMA unnecessarily complains that I am using SingleTableMetadata.

FutureWarning: The 'SingleTableMetadata' is deprecated. Please use the new 'Metadata' class for synthesizers.

I expect that there should be no such warning because I am using the correct Metadata object.

Steps to reproduce

Use the fake_hotels demo dataset to replicate. The download_demo provides the new, streamlined Metadata object so there should be no warning.

from sdv.datasets.demo import download_demo
from sdv.multi_table import HMASynthesizer

real_data, metadata = download_demo(modality='multi_table', dataset_name='fake_hotels')

custom_synthesizer = HMASynthesizer(metadata, verbose=False)
custom_synthesizer.set_table_parameters(
    table_name='hotels',
    table_parameters={ 'default_distribution': 'truncnorm' })
custom_synthesizer.fit(real_data)

FutureWarning: The 'SingleTableMetadata' is deprecated. Please use the new 'Metadata' class for synthesizers.

Additional Context

Note that the warning goes away if I just use the default HMA (i.e. I do not apply set_table_parameters)

default_synthesizer = HMASynthesizer(metadata)
default_synthesizer.fit(data)
