Suggested mapping overrides help's K

In help files K can be used to jump to topic under the cursor. Suggested mapping overrides it. Neovim hover handler (vim.lsp.buf.hover) which I think many users have also mapped to K through on_attach function will not have that issue as it will not be mapped for help files. It makes sense to create global mapping for hover.nvim as it's useful beyond files with LSP attached. I have came up with following guard, not sure if it's the right way of doing it, but perhaps you can think of better way and update readme accordingly?

vim.keymap.set('n', 'K', function()
  if vim.bo.filetype ~= 'help' then
    require('hover').hover()
  end

  vim.api.nvim_feedkeys('K', 'ni', true)
end)

Start by reviewing the hover.nvim README and the suggested global K mapping in the issue. Check how the mapping interacts with help buffers and the existing hover entry point, then document the supported behavior and verify that K still opens help topics while invoking hover elsewhere.
