Fix searching through all help documents not working due to migrating from PySide2 to PySide6

closes #147 (closed)

'tree_view.update()' need to be removed for PySide6.

However we are going to go back to PySide2 until the end of 2023 when qpeek and logpeek are removed from passoft. So we will leave this not merged until then.
