fix: update chip support content

[f-hollow]

Description

This PR returns the content that disappeared during the work on #376 . Preview page: ESP32-C61 support status.

The file ESP32-C61.md that is dynamically fetched was sliced up into several types of content. We sliced up a newly-generated file which did not have the manually added lines (the External project section) in the previous version of ESP32-C61.md.

The dynamically fetched content is not visible. We will implement pulling the latest JSON files from the script repo to previews a bit later.
