error opening file when window.width is not lua number and neo-tree is only opened window #789
Description
When I set window.width to a string or a function, neo-tree throws an error when trying to open a file when neo-tree is the only window open.
It works fine when I have neo-tree open and another window open, only when neo-tree is the only buffer open, it breaks.
Example setup:
require("neo-tree").setup({
window = {
width = "30%"
}
})Error code:
E5108: Error executing lua: ...cal/share/nvim/lazy/neo-tree.nvim/lua/neo-tree/utils.lua:508: Expected lua number

From my understanding of the code, I'm guessing it works normally because neo-tree uses nui to open the split, and nui accepts percentages and functions. However, when opening a file when neo-tree is the only window, vim.api.nvim_win_set_width is called and window.width is passed without any extra processing.
Perhaps the code similar to calc_container_width could be used, as container width support strings and functions already.
