fix(esp-idf): pin midi2 dependency to git tag v0.3.3

ESP-IDF Component Manager interprets `version:` for git deps as a
literal git ref (branch / tag / SHA), not a semver constraint. The
previous `version: ">=0.3.3"` failed configure with
"Git reference >=0.3.3 doesn't exist in the repository".

Pin all seven ESP-IDF recipes to `version: "v0.3.3"`.

Verified locally: esp32-s3-devkitc-usb-midi2 now reconfigures and
the full build links a flashable .bin against midi2 v0.3.3.
