[Bug] Invalid directory name generated by installation script

[haruleekim]

rocks.nvim/installer.lua

Line 157 in 33d8521

local tempdir = vim.fs.joinpath(vim.fn.stdpath("run"), "luarocks-" .. vim.loop.random(7))

The code vim.loop.random(7) in the above possibly generates a directory name that is treated as invalid by the OS.
For example: luarocks-<a1><ec>^O<98>^^{<f8>.

Therefore, I suggest changing that line to the following:

local tempdir = vim.fs.joinpath(vim.fn.stdpath("run"), string.format("luarocks-%X", math.random(256 ^ 7)))

Hey 👋
Thanks for reporting!

Your proposed solution looks reasonable to me. @vhyrro what do you think?
