Environment details

• OS type and version: Windows 11
• Python version: 3.11.9
• pip version: 24.0
• google-cloud-bigquery: 3.16.0

Steps to reproduce

1. get TableReference with a table name containing a wildcard
2. call the get_table method to obtain the Table instance
3. access to modified property

Code example

from google.cloud import bigquery

client = bigquery.Client(project="your-project")

table_ref = client.dataset("your_dataset").table("dummy_*")
table = client.get_table(table_ref)

print(table.modified)

Stack trace

No error happens.

It is reasonable that the get_table method only works when given an exact table name.
However, shouldn't it at least raise an error or warning instead of just returning the current timestamp?
