feat: Adding Keyboard Incognito

[saisafe]

Closes #3855 (really old!)
label: exclude

The suggestion of the issue was to add settings toggle under privacy but looks better as a default privacy protection.

Hi @saisafe,

I apologize for the delay in reviewing these changes.

After discussing them with the team, we find these changes quite interesting and would like to have them added to the app. However, we believe that the decision to enable the keyboard in incognito mode should be left up to the user, rather than mandated by us.

To proceed with accepting this PR, you will need to introduce a user setting that allows users to enable or disable this feature at their discretion, with the default setting being off, as it is currently.

Please refer to our documentation to learn more about implementing User Settings. If you need any assistance with making these changes, feel free to reach out to me.

Thank you for your understanding!

Hi @rafaeltonholo

Thank you for the update.

Noted, I'll add the user setting under general settings>privacy.

I need help with the title for the user setting and hope the description is "disables google keyboard from training user words."
