[Feature Request] Setting for case-insensitive require resolution?

Priority
Low

Description
On Windows and Mac, file systems are case-insensitive by default. Lua's filepath resolution is based on the OS, so I feel like while only the exact spelling for a file should be autocompleted, when actually resolving the type of a module, lua-language-server should have an option to be case-insensitive.

Example

root/
├── myscript.lua
└── mymod.lua

-- myscript.lua --
local myMod = require "myMod"

Currently you can write a plugin similar to the one below using ResolveRequire

local libRoot = fs.current_path() / "library"

local function resolveCaseInsensitive(root, moduleName)
    for file in fs.pairs(root) do
        if fs.is_regular_file(file) then
            local fileName = file:filename():string()
            if fileName:lower() == (moduleName .. ".lua"):lower() then
                return file:string()
            end
        end
    end
end

---@param  uri  string # The URI of file
---@param  name string # Argument of require()
---@return string[]?
function ResolveRequire(uri, name)
    local libModuleFile = resolveCaseInsensitive(libRoot, name)
    local localModuleFile = resolveCaseInsensitive(fs.path(furi.decode(uri)), name)

    local result = {}
    if libModuleFile then
        result[#result+1] = furi.encode(libModuleFile)
    end
    if localModuleFile then
        result[#result+1] = furi.encode(localModuleFile)
    end

    if #result ~= 0 then
        return result
    end
end

Alternatively, I propose that a spellchecking diagnostic could be introduced for resolving module names. If a name matches the name of a known module in all except its case, a blue or yellow squiggly would underline the string, and the message could be something like "did you mean 'otherName'". This could be an opt-in diagnostic if it is considered a breaking change.

Inizia con l’hook del plugin ResolveRequire esistente e segui il percorso di risoluzione dei moduli di require(). Determina se il progetto debba implementare un’impostazione senza distinzione tra maiuscole e minuscole oppure una diagnostica opt-in, quindi individua i test pertinenti. Il lavoro è completato quando il comportamento selezionato gestisce le differenze nelle maiuscole e minuscole dei nomi dei moduli su Windows e macOS ed è coperto da test.
