filterPlaceholder parameter of filterParams has no effect on Date filter

According to the docs, the filterPlaceholder parameter of filterParams can be assigned to Date filters. I have tried to provide them as various string formats, but it has no effect on the placeholder text, even when the browserDatePicker property is set to False.

I suspect this is not an issue with dash-ag-grid but with ag-grid itself: https://github.com/ag-grid/ag-grid/issues?q=label%3AAG-3735+is%3Aclosed. As the issue has been in their backlog for quite some time, I think it would be necessary to remove this parameter from the docs. If there is a way to override the locale (since the date format is locale dependent for the Date selector), could you please provide an example?

Start by running the provided Dash MRE and comparing the Date filter behavior with the documented filterPlaceholder parameter, including browserDatePicker set to false. Review the linked AG Grid issue and the project documentation for this parameter; done means confirming the limitation and either removing the misleading documentation or adding a verified locale example.
