Remove misleading address field from Ray Task

[Sovietaced]

Tracking issue

Closes flyteorg/flyte#5877

Why are the changes needed?

The documentation implies that you can run a ray job on an existing cluster by configuring the address but this is not true since the task still requires users to configure details for a new and dynamically created Ray Cluster. And ray jobs will run on the dynamically created Ray Cluster even if an address is configured.

Check all the applicable boxes

• I updated the documentation accordingly.
• All new and existing tests passed.
• All commits are signed-off.

This is backwards incompatible right?

This is backwards incompatible right?

Correct. If we want to keep backwards compatibility I can close this. I was't sure how stable these plugins are meant to be, especially this one.

thanks. I think this only works for local execution. For those people who still want to use it, they can use RAY_ADDRESS env.
