Updating pyre version after old version expired

[mgrange1998]

Summary: Pyre in Ax stopped working suddenly for multiple devs with the error message

File "tools/pyre/facebook/client/environment.py", line 264, in download_from_manifold
    raise ManifoldDownloadException(response.reason)
tools.pyre.facebook.client.environment.ManifoldDownloadException: Not Found"

Looking into the message, it has been seen when Pyre packages have expired: https://fb.workplace.com/groups/pyreqa/permalink/6561314563958320/

The fix is to update the pyre version in Ax to one still in retention. Updating the version caused many new Pyre errors, so also ran

pyre --output=json | pyre-upgrade

To add fixmes to them
