Fix swapped W5500 clk/miso pins on Waveshare ESP32-S3-ETH

[bdraco]

What does this implement/fix?

A device generated from the Waveshare ESP32-S3-ETH board failed to bring up its onboard W5500 at boot:

w5500.mac: W5500 version mismatched, expected 0x04, got 0x00
emac_w5500_init(883): verify chip ID failed

The board manifest had clk_pin: GPIO12 and miso_pin: GPIO13, but Waveshare's pinout is SCLK GPIO13 and MISO GPIO12. With MISO listening on the SCLK line the chip-ID read came back all-zeros, so ethernet never initialized. This swaps the two pins (and the matching occupied_by pin annotations) and regenerates the catalog. MOSI/CS/INT/RST and 25MHz were already correct.

The transposition slipped through because both pins are valid GPIOs, so esphome config accepted it; only flashing real hardware surfaced it. Verified against Waveshare's ETH_DHCP pin table and confirmed on hardware (W5500 now initializes, link plus DHCP).

PR Review — Fix swapped W5500 clk/miso pins on Waveshare ESP32-S3-ETH

Correct, hardware-verified pin swap. Merge-ready.

• Swaps clk_pin GPIO12→GPIO13 and miso_pin GPIO13→GPIO12 to match Waveshare's documented ETH_DHCP pinout (SCLK GPIO13, MISO GPIO12), fixing the W5500 chip-ID read failure.
• Change is internally consistent across all three generated artifacts: manifest.yaml featured_components + pin occupied_by annotations, board_bodies/waveshare-esp32-s3-eth.json, and the regenerated featured_components.index.json (omitted from diff but listed as changed; current main still carries the old GPIO12/GPIO13 values, confirming the regen is needed and included).
• Scope is tight and matches the description — only the two transposed pins touched, MOSI/CS/INT/RST/clock_speed untouched. Correctly labeled bugfix, no frontend change.
• No test added, but the failure mode (two valid GPIOs that esphome config accepts) is not catchable without real hardware, as the PR notes; script/validate_definitions.py covers manifest structure, not electrical correctness.

Pull request overview

Fixes an incorrect SPI pin mapping in the Waveshare ESP32-S3-ETH board definition so generated configs can reliably initialize the onboard W5500 Ethernet controller at boot.

Changes:

• Swap W5500 clk_pin and miso_pin values in the Waveshare ESP32-S3-ETH board manifest to match the vendor pinout.
• Update the corresponding pins[].occupied_by annotations for GPIO12/GPIO13.
• Regenerate the board body JSON so the shipped catalog reflects the corrected pins.
