[skip changelog] Pin platform versions used in integration tests (#879)

This prevents spurious test breakage caused by platform releases. These tests are about the behavior of Arduino CLI itself, not about testing the platform, so the platform should be static. There are certain tests which make sense to do with the latest release of the platforms, and those have been left as is.
