Delta Lake Duration data type

[gam-phon]

Checks

• I have checked that this issue has not already been reported.
• I have confirmed this bug exists on the latest version of Polars.

Reproducible example

import polars as pl
from datetime import timedelta

data1 = [
    {"d": timedelta(days=2), "k": "ds"},
]
df = pl.DataFrame(data1)
df.write_delta("delta_lake")

Log output

File ".venv/lib/python3.12/site-packages/polars/dataframe/frame.py", line 4066, in write_delta
write_deltalake(
File ".venv/lib/python3.12/site-packages/deltalake/writer.py", line 543, in write_deltalake
write_deltalake_pyarrow(
_internal.SchemaMismatchError: Invalid data type for Delta Lake: Duration(Microsecond)

Issue description

In the documentation we did not mention that duration is not supported.
In docs it is written
The Polars data types :class:`Null` and :class:`Time` are not supported by the delta protocol specification and will raise a TypeError.

mentioned in this comment #16454 (comment) @ion-elgreco

Expected behavior

Maybe write in the documentation. we do not support duration, since it is not supported yet by delta or we work around it by serialization/deserialization like what is proposed in the link
