This reverts commit e8db92f7, reversing
changes made to 4201f517.

When search fails due to a non-standard encoding, show a notification to help people find the new setting

was triggered by an option change

In these cases, the programmer has explicitly indicated that the type should be nullable

Introduces a new settings option "search.useReplacePreview" which
allows you to disable "Replace Preview" during a Search/Replace.

Closes #60027

Using a custom version of the node typings is causing a lot of pain while trying to upgrade our build to use `@types` instead of the `d.ts` files we have to maintain. I believe we primarily maintain our own version for two reason:

- Custom require function
- setTimeout and other timer functions return NodeJs.timer instead of a number

These can both be delt with, the first by using interface augmentation and the second by switching to use any types for timer. I believe that the pain of maintaining our own node `d.ts` outweighs the benefits here

This change switches us to use the standard @types/node package for our node typings

We compile using the alwaysStrict flag so these directives are not needed

Fix #52590 - don't move focus when clicking the search details buttons with screenreader mode turned on.
Because NVDA sends click events instead of key events when pressing space.
Also update this dynamically for the search option buttons

Fix #52274 - don't move focus when clicking the find option buttons with screenreader mode turned on, because NVDA sends click events instead of key events when pressing space on a focused button
