Italics harcoded for builtins - should have setup option?

[WVAviator]

I don't like italics in code, and wanted to disable all of them. However, there's no way to disable italics for builtins (i.e. self or this) in the default setup options. After some digging I found that I can set italic = false in the overrides for @variable.builtin, but this was not obvious. The option italic = true is hardcoded for this hlgroup.

require("kanagawa").setup({
  commentStyle = { italic = false },
  keywordStyle = { italic = false },
  overrides = function()
    return {
      ["@variable.builtin"] = { italic = false },
    }
  end
})

While the above config works, what I would like is to be able to do is configure options for builtins similarly to other styles - with italic = true as a default instead of being hardcoded. Something like this:

require("kanagawa").setup({
  commentStyle = { italic = false },
  keywordStyle = { italic = false },
  builtinStyle = { italic = false },
})

If this is infeasible, then perhaps it can be listed in the README under Common Customizations. Surely I'm not the only person who dislikes italics in code.

We want the same for bold.
