fix: Correct Class name for the ClientInfo class

[JakeChampion]

It is currently named FetchEvent, which can lead to confusion when logging out the value. For example this application logs the client info prototype and the fetch event prototype:

addEventListener("fetch", event => event.respondWith(handleRequest(event))) async function handleRequest(event) { console.log(event.client.__proto__) console.log(event.__proto__) return new Response; }

The log lines look like this:

Log: FetchEvent { address: [Getter], geo: [Getter], tlsCipherOpensslName: [Getter], tlsProtocol: [Getter], tlsJA3MD5: [Getter], tlsClientCertificate: [Getter], tlsClientHello: [Getter] } Log: FetchEvent { client: [Getter], request: [Getter], respondWith: [ function respondWith() {[native code]}], waitUntil: [ function waitUntil() {[native code]}] } 

We can see that the class name is included in the log and they both have the class name FetchEvent right now
