Update the Waveshare ESP32-S3-Zero board manifest

[bdraco]

What does this implement/fix?

Updates the Waveshare ESP32-S3-Zero board manifest with the correct hardware facts (4 MB flash, 2 MB PSRAM, 18x23.5mm), moves the onboard WS2812 RGB LED to GPIO21, and marks the pins that are not broken out as unavailable. The body JSON and index are regenerated from the manifest with script/sync_boards.py so the shipped catalog matches the manifest; this finishes the work in #1640, where the generated files were out of sync.

Superseded; pushed the regeneration fix directly to #1640 instead.
