p-columnFilter: Missing icons to the table column filter dialog

[rosenthalj]

Describe the bug

The PrimeNG table's column filter dialog is missing the "trash" and "plus" icons.

The icons were in PrimeNG v14 (and earlier) but were "lost"

The first and second annotated screenshots are of the PrimeNG v17 table filter menu demo (https://primeng.org/table#filter-menu) showing the table's column filter dialog missing "plus" and "trash" icons.

The third and forth annotated screenshots are of the PrimeNG v14-lts table filter menu demo (https://www.primefaces.org/primeng-v14-lts/table#filter-menu) showing the table's column filter dialog with the "plus" and "trash" icons.

Examining the table.ts code, the TrashIcon and PlusIcons are actually included with the column filter dialog:
