Subject: [PATCH] Fix accessory power rail labels on SEN65 page (#1138)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The check step told readers to look for "Accessory Power Rail" in the
Components list. That is the name on the component picker card, not what the
config shows. In the Components navigator it appears as a GPIO Switch named
Accessory Power, so the step pointed at a label that is not there.
Verified in Device Builder 1.14.7: the picker hides a featured component once
the device has it, which is why the card is missing for anyone who already has
the rail. Add a step for the case where it is genuinely absent, and correct
Add Component to Add component throughout.
