Using the `actions_before` parameter in Get a Board API returns results for ALL dates

Issue Summary

The `actions_before` parameter does not filter correctly.

Steps to Reproduce

1. Use the Get a Board API
2. Refer to the Nested Resource for Actions on how to use the actions_before and actions_since parameters
3. Do a GET on this endpoint and replace BOARD_ID, TRELLO_KEY, TRELLO_TOKEN with your own values:

   https://api.trello.com/1/boards/BOARD_ID?actions=all&actions_before=2024-04-15&action_fields=date&key=TRELLO_KEY&token=TRELLO_TOKEN 

Expected Results

Returns results from before 2024-04-15

Actual Results

Returns results on all dates, including the latest ones (after 2024-04-15)
The `actions_since` parameter works as expected.

Workaround

Use the Get Actions of a Board API and the `before` parameter.
