Reference full service call example

[bcutter]

Note the existing example for a usage inside a full service call to avoid confusion with data inside data (following home-assistant/core#84645 (comment))

Proposed change

Helps avoiding confusion with nested use of data:.
Instead of adding an additional full service call example, let's just redirect to the existing one at the end of the page (unfortunately example snippets don't have an anchor which would allow to link to).

Type of change

• 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).
  • 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.
