Snowflake exclude incorrect parsing

[diogo-fernan]

Hi! sqlglot seems to be incorrectly parsing exclude for single columns when no parenthesis are used. Having no parenthesis is valid Snowflake syntax.

Thoughts?

import sqlglot

sql = """
select
    * exclude b  -- incorrectly parsed
    ,b
    ,c
from
    test
;
"""

print(sqlglot.parse_one(sql, read="snowflake"))

sql = """
select
    * exclude(b) -- correctly parsed
    ,b
    ,c
from
    test
;
"""

print(sqlglot.parse_one(sql, read="snowflake"))

# output:
# SELECT * EXCEPT (b /* incorrectly parsed */, b, c) FROM test
# SELECT * EXCEPT (b) /* correctly parsed */, b, c FROM test

Thanks for the report @diogo-fernan, looks like this was an oversight on our end.
