Display :RMapsDesc and :RConfigShow in a split buffer instead of as an nvim_echo() statement

[kkanden]

This change will make outputs of these two commands display in a separate buffer, which will allow for easier navigation and searching for specific commands, mappings and config options. This will also mimic the behavior of :h making it less dizzying.

Thanks for your contribution! Please, create a symbolic link to scripts/pre-commit as explained in CONTRIBUTING.md and run stylua:

cd /path_to/R.nvim
stylua lua

Maybe we could add this to the buffers (as we do for R documentation):

    vim.api.nvim_buf_set_keymap(0, "n", "q", ":q<CR>", { noremap = true, silent = true })

Perhaps we shouldn't use a buffer when an argument is passed to :RConfigShow because a single value is displayed. Example:

:RConfigShow compldir

Although it might be a table:

:RConfigShow compl_data

What do you think about these suggestions?

I think those are good ideas. I forgot that you could pass na argument to :RConfigShow. Maybe if an argument is passed, the value of that option could just be displayed using nvim_echo() as it is now, and if no argument is passed, only then display it in a buffer?

Yes, I agree.

I've implemented the suggestions. I have also added highlighting to the keywords in :RConfigShow for better looks :)

Thank you! It was a good improvement to the two commands!
