Remove options_flow from laundrify integration

[xLarry]

Proposed change

The options flow need to be removed from the laundrify integration docs, since it has been removed during code review (see home-assistant/core#65090 (comment)).

I am targeting the next branch, since the laundrify integration will be released in the upcoming 2022.6 release and is not part of the current documentation.

Type of change

• Spelling, grammar or other readability improvements (current branch).
• Adjusted missing or incorrect information in the current documentation (current branch).
• Adjusted missing or incorrect information in the upcoming documentation (next branch).
• Added documentation for a new integration I'm adding to Home Assistant (next branch).
  • I've opened up a PR to add logo's and icons in Brands repository.
• Added documentation for a new feature I'm adding to Home Assistant (next branch).
• Removed stale or deprecated documentation.

• Link to parent pull request in the codebase: Add laundrify integration core#65090
