Unreachable code in shard.py

[GDOlivercoding]

Summary

I found an unreachable error case in discord.shard or shard.py

Reproduction Steps

Hello! I found an unreachable error case in https://github.com/Rapptz/discord.py/blob/master/discord/shard.py#L520-523 this snippet here when i was browsing the library code,

the snippet is as follows:

                   if item.error.code != 1000:
                        raise item.error
                    if item.error.code == 4014:
                        raise PrivilegedIntentsRequired(item.shard.id) from None

as you can see, the second error case is completely unreachable, as in order to reach there .code must be 4014, which it cannot

further more, setting type checker mode to strict will show us this error:

Condition will always evaluate to False since the types "Literal[1000]" and "Literal[4014]" have no overlap

https://github.com/Rapptz/discord.py/blob/master/discord/shard.py#L151-L157
here is an example where it is correctly written

Minimal Reproducible Code

code = 4014
if item.error.code != 1000:
    raise ValueError("generic raise")
if item.error.code == 4014:
    raise ValueError("specific raise")
