Redundant escapeHTML Setting in go-chi/render

https://github.com/go-chi/render/blob/14f1cb3d5c2969d6e462632a205eacb6421eb4dc/responder.go#L95C2-L96C25

In the `responder.go` file, the JSON function sets `escapeHTML` to true.
However, the `json.NewEncoder` defaults to `escapeHTML: true`.
This appears to be redundant.

Source code for json.NewEncoder:
```
func NewEncoder(w io.Writer) *Encoder {
return &Encoder{w: w, escapeHTML: true}
}
```
