[aur-requests] [PRQ#35693] Merge Request for arduino-pro-ide

SuperNinja_4965 [1] filed a request to merge arduino-pro-ide [2] into arduino-ide-beta-bin [3]: As of March 1st, 2021 the Pro IDE became open source under the name of Arduino IDE 2.0. Its development is hosted in a new repository located at https://github.com/arduino/arduino-ide. hence this package is no longer needed as a new package was created by another user.
