Describe the bug

If you filter for only true, it filters the table correctly.
But after open the menu again, it doesn't display the checkbox as selected as it should for the active true filter.
The checkbox is completely reseted.

For the other types of filters you can open the menu again and it shows the correct selected filter.

In previous primeng versions there were an "active" css class for the icon, too.

Steps to reproduce the behavior

Go to the original example https://primeng.org/table#filter-advanced
Filter the "Verified"-Column for "true"
"Apply" the filter and the menu will close.
Open the filter menu again
You see now, that the checkbox isn't selected, although the filter is still set.

Expected behavior

Checkbox inside the menu should represent the correct state of the filter

The icon or button of the columnfilter should have a class like "active" that represent the active state of the filter like in previous primeng versions
