[UI Tests] Peek - fix UI tests via setting hotkeys back to Ctrl+Space combo for tests only (#43168)

This pull request introduces a static initialization step to the
`PeekFilePreviewTests` class to ensure the correct test settings are
present before tests run. The main change is the addition of a static
constructor that creates or updates the `settings.json` file with
predefined settings, including setting the activation shortcut to
Ctrl+Space.

Test setup improvements:

* Added a static constructor to `PeekFilePreviewTests` that calls a new
`FixSettingsFileBeforeTests` method, ensuring the necessary settings
file exists and is properly configured before any tests execute.
* Implemented `FixSettingsFileBeforeTests` to create the required
directory and write a `settings.json` file with specific test
configuration, including setting the activation shortcut to Ctrl+Space
and other test-relevant properties.
