Pandas version checks

• I have checked that this issue has not already been reported.

• I have confirmed this bug exists on the latest version of pandas.

• I have confirmed this bug exists on the main branch of pandas.

Reproducible Example

import pandas as pd

pd.to_numeric(pd.Timedelta(1))

Issue Description

Getting a TypeError

Expected Behavior

For the example above, I should get the integer 1. That would match the behavior of pd.to_numeric(pd.Series(pd.Timedelta(1)))
