Avoid creating a new instance of the ObjectMapper ctd.

Bug Report

Current Behavior

This follows up on #3370, which got fixed in #3372. While the ObjectMapper is now reused for parsing, a new instance is still created inside DelegateJsonValue#toObject every time it is called.

Input Code

Input Code

@Override
public <T> T toObject(Class<T> type) {
    ObjectMapper mapper = new ObjectMapper();
    try {
        return mapper.treeToValue(node, type);
    } catch (IllegalArgumentException | JsonProcessingException e) {
        throw new RedisJsonException("Unable to map the provided JsonValue to " + type.getName(), e);
    }
}

Expected behavior/code

Reduce the amount of new objects being created when working with JSON.

Environment

• Lettuce version(s): 6.8.0.RELEASE and up
• Redis version: any

Possible Solution

Pass the ObjectMapper configured on the DefaultJsonParser to DelegateJsonValue and its subclasses.
