getGroupMember does not handle 404s correctly

[SticksDev]

When testing my API service, I noticed that if you pass an invaild user id or a user that doesn't exist into getGroupMember, it won't surface the 404 from VRC. On the latest version (2.20.5). Here's the error I get when this happens

and the code I used to check if this is an error from the lib:

if (groupMemberError || !response) {
        console.log('groupMemberError', groupMemberError);
        console.log('response', response);
        if (groupMemberError instanceof VRChatError) {
            if (groupMemberError.statusCode === 404) {
                return c.json(APIErrors.groups.groupNotFound, 404);
            }
        }
        logger.error(
            `Error fetching group member ${userId} for group ${groupId}:`,
            groupMemberError,
        );
        return c.json(APIErrors.groups.errorFetchingMember, 500);
    }

We are dropping past the VRChatError case because of the internal error. Let me know If I need to provide or do anything to get this fixed.

Thanks!

getGroupMember returns a 200 with a null body for unknown members, rather than throwing a 404. The specification currently documents it as returning a 404, which causes the SDK generation to fail.

Feel free to open a PR to update the specification.
