fix!: duckdb week/quarter support

[eakmanrq]

This logic was originally added in 2023: #1780

I can see quarter was at least added in 2024: duckdb/duckdb#11898

Tested and confirmed that 0.10.3 added quarter support and week support is in 0.10.2 so not sure when that was added.

The original logic actually has a bug for quarter since it converted a quarter to 90 days but that isn't correct when doing additions and subtractions to dates.

conn.execute("SELECT DATE_ADD(TIMESTAMP'2020-01-01 00:00:00', INTERVAL 1 QUARTER)").fetchall()
[(datetime.datetime(2020, 4, 1, 0, 0),)]
conn.execute("SELECT DATE_ADD(TIMESTAMP'2020-01-01 00:00:00', INTERVAL 90 DAY)").fetchall()
[(datetime.datetime(2020, 3, 31, 0, 0),)]

The previous week logic looks fine but isn't needed anymore:

conn.execute("SELECT INTERVAL (-5) WEEK").fetchall()
[(datetime.timedelta(days=-35),)]
