Fix: Switch default `to_koalas` in `HiveData._read_table`. to False

[Vincent-Maladiere]

Description

The to_koalas argument has been deprecated in _read_table since it wasn't used. Returning koalas DataFrame during this step allows for more predictable behavior and fewer worries due to OOM errors.

When to_koalas is set to True, we raise a warning to indicate that this argument is not used. Since this argument is True by default, we raise this warning for every table to be read, which is unpleasant for the user.

Therefore, this PR suggests setting to_koalas to False by default.
