Support multiple config files

[SnowSquire]

miniflare now supports multiple config files for running 2 workers in the same instance cloudflare/workers-sdk#7251.

declare module "nitropack" {
    interface NitroOptions {
        cloudflareDev?: {
            configPath?: string;
            environment?: string;
            persistDir?: string;
            silent?: boolean;
        };
    }
}

should be changed to

declare module "nitropack" {
    interface NitroOptions {
        cloudflareDev?: {
            configPath?: string | string[];
            environment?: string;
            persistDir?: string;
            silent?: boolean;
        };
    }
}

this would be greatly appreciated as currently i can't do durable object rpc in dev
