`FCVAR_*` constants produce warnings for `CreateConVar`

[b0mbie]

Doing something like:

CreateConVar("enable_the_thing", '1', FCVAR_REPLICATED)

... will make LuaLS erroneously produce a warning:

Cannot assign `integer` to parameter `(`FCVAR_ARCHIVE_XBOX`|`FCVAR_ARCHIVE`|`FCVAR_CHEAT`|`FCVAR_CLIENTCMD_CAN_EXECUTE`|`FCVAR_CLIENTDLL`...(+19))?`.
- `integer` cannot match `(`FCVAR_ARCHIVE_XBOX`|`FCVAR_ARCHIVE`|`FCVAR_CHEAT`|`FCVAR_CLIENTCMD_CAN_EXECUTE`|`FCVAR_CLIENTDLL`...(+19))?`
- Type `integer` cannot match `nil`
- Type `number` cannot match `nil`
- Type `integer` cannot match `number[]`
- Type `number` cannot match `number[]`

I can only assume that this is somehow because of either the type definition for FCVAR, or the type of the FCVAR_* constants.

Thanks again for reporting, I really appreciate it!

I'll have to look into this sometime. It might be related to what we changed in #71:

glua-api-snippets/library/enums.lua

Line 4503 in 0117ea1

---@alias FCVAR

Since this wasn't an issue when we worked on it then (or at least I don't recall it being a problem), something may have changed in LuaLS recently that caused this.
