In the Rain Forest greenhouse of Biosphere 2, there is a forest with 90 species that is 25 years old. Being in a greenhouse in Arizona, why hasn't the heat trapped in the greenhouse baked this forest?

Among other things, it's at about 4000 feet.  It's substantially cooler that high.  It's relatively close to the Mt. Lemmon ski area-- which is a couple hours *south* of Phoenix.  It sounds crazy that there's skiing in Arizona that's further south even than the fiery death-zone of Phoenix... but the change in altitude makes it possible.

Oracle is, on average, about 20 degrees cooler than Phoenix.

This probably doesn't explain all of it, but it does help explain why it's not quite as bad as "a greenhouse in arizona" might suggest.
