Add overload to WithEndpoint WithHttpEndpoint etc that allows you to set DisplayText outside of WithUrl

### Is there an existing issue for this?

- [x] I have searched the existing issues

### Is your feature request related to a problem? Please describe the problem.

If you're simply trying to name an endpoint you create (in my case, the proxy to a Vite frontend app), it feels a little chunky to do
`WithHttpEndpoint().WithUrlForEndpoint("", => {})`

ie

```
var frontend = builder.AddPnpmApp("frontend", "../frontend")
.WithPnpmPackageInstallation()
.WithReference(ratingsApi)
.WithHttpEndpoint(name: "vite-port", targetPort: 5173)
.WithUrlForEndpoint("vite-port", url =>
{
url.DisplayText = "Frontend (Vite)";
});
```

### Describe the solution you'd like

Would love an overload on WithHttpEndpoint etc that allows passing "DisplayText" as a param, ie

` .WithHttpEndpoint(name: "vite-port", targetPort: 5173, displayText: "Frontend")`
