date_trunc output from fast path does not contain timezone information #18597
Description
Describe the bug
date_trunc output from the fast path does not contain timezone information.
A check is recently added to invoke_with_args that checks for the output type of the result with the expected output type from the UDF - #17515. Because the fast path misses adding the timezone, the assertion added in this PR fails.
