Remove unrelated esp32 stanza from example code

[Elwell]

Description:

This page describes the 'esphome' section so doesn't need to include the esp32 section which itself includes the old 'board' line rather than the preferred 'variant' setting

Checklist:

• I am merging into next because this is new documentation that has a matching pull-request in esphome as linked above.
  or

• I am merging into current because this is a fix, change and/or adjustment in the current documentation and is not for a new component or feature.

• Link added in /components/index.rst when creating new documents for new components or cookbook.
