[Request] Add keyboard support for Start Page

[limodual]

Just like keyboard support in Grid view in Playnite, it would be really nice to have keyboard support where you can navigate the games in Start Page with arrows to navigate and enter button to start the game. Also you can able to use Start page with a controller by assigning keyboard keys with a controller buttons with a suitable apps like Controller companion. I hope felixkmh will bring this feature to live.
