Can not scroll through documentation window

[YouRik]

Describe the bug

Using <C-f> and <C-b> as defined in the init.lua to scroll through the documentation window does not work. Instead, they scroll up and down the worked on buffer by one full page. See: https://github.com/nvim-lua/kickstart.nvim/blob/4120893b8a1f31a0957f2f891f7fbef73ddfb9b1/init.lua#L771-L773

To Reproduce

1. Install kickstart.nvim
2. Install some LSP for a programming language (in my case Python and Pyright)
3. Open a file for that programming language
4. hit <S-K> to hover over a symbol that has documentation and observe the documentation window appear
5. Press <C-f> or <C-b> and observe that it's not scrolling the documentation
