Hide keyboard suggestions when typing answers

###### Reproduction Steps

1. View a card with `{{type:Front}}`
2. On the latest Android 12 and Gboard on a Pixel 6, I see predictive text suggestions when typing my answer.

###### Expected Result

No text suggestions should be displayed. I've found an old issue that is closed now saying this used to be an issue but was fixed: https://github.com/ankidroid/Anki-Android/issues/3727. There was a more recent issue where this was mentioned, but it was closed: https://github.com/ankidroid/Anki-Android/issues/8708.

I know it may be tricky to fix this for all versions of Android and various keyboards, but I feel like we should at least make sure this doesn't happen in the latest Android release with the stock/default keyboard.

###### Actual Result
