Upgrade to GraphQL Java 23.0

This commit upgrades to GraphQL Java 23.0.

Because this new version brings in java-dataloader 4.0.0, this commit
also adapts to a breaking change there. `DataLoaderOptions` is now
immutable and calling setters on it will return a new instance.
As a result, this commit also changes the `BatchLoaderRegistry` to
customize the dataloader by consuming a `DataLoaderOptions.Builder`
instead of a `DataLoaderOptions` directly. This only breaks binary
compatibility as both `DataLoaderOptions` and `DataLoaderOptions.Builder`
have identical APIs.

Closes gh-1169
