Remove API Key instructions from Hydrawise docs

[dknowles2]

Proposed change

Remove the prerequisites section from the Hydrawise docs that discuss the need to obtain an API Key. This is no longer necessary with https://github.com/home-assistant/core/pull/106904 as you can now simply authenticate using username & password.

• [ ] Spelling, grammar or other readability improvements (current branch).
• [ ] Adjusted missing or incorrect information in the current documentation (current branch).
• [ ] Added documentation for a new integration I'm adding to Home Assistant (next branch).

Let's rebase this to current so we can get this in. If you ever notice that we forget to merge the docs (or label it for that matter) but the feature did, be sure to let us know on discord :)

I note that because I authenticate via Apple, I don’t have a password. Does this mean I have to create a new account using my email address to use this integration now? Or is there some way to get the authentication dialog in the integration linked to the Apple authentication page?

It seems that this PR is targeted against an incorrect branch since it has a parent PR on one of our codebases. Documentation that needs to be updated for an upcoming release should target the next branch. Please change the target branch of this PR to next and rebase if needed.
