fix: update osk patch to fix more corner cases

This is a follow up to #35921
that, it fixes more corner cases that on-screen-keyboard does not hide
for webviews.

This change has been applied in Teams for quite a while and should be
reliable enough to introduce to Electron.

 Subject: fix: on-screen-keyboard hides on input blur in webview
 
-Changes introduced by this patch fix issue where OSK does not hide on
-input rendered inside webview is blurred. This patch should be removed
-when proper fix in chromium repo is available.
-
-Note: the issue still occurs if input rendered in webview blurred due
-to touch outside of webview. It is caused by webview implementation
-details. Specificaly due to webview has its own tree nodes and focused
-node does not change in this case.
+Work around OSK not hiding by notifying RenderWidgetHostViewAura of
+focus node change via TextInputManager.
