Cache Platform

[Yee36951]

Describe the request

Cache the downloaded Arduino platform

Every time an Action is executed, the platform needs to be downloaded. However, the files downloaded by a single version are almost the same, and they are all huge. We hope to reduce the running time of the Action by caching the platform.

Describe the current behavior

        run: |
          arduino-cli core update-index
          arduino-cli core install esp32:esp32 --additional-urls https://espressif.github.io/arduino-esp32/package_esp32_index.json

'arduino/setup-arduino-cli' version
