zimbatm 9f2ff1d31a terraform: revamp the providers list (#29097)
This fixes the ./update-all script to actually fetch all the available
providers (thanks pagination). It was also improver to user a more
compact representation of the data.

Missing the GITHUB_AUTH env. Thi is required to work around the 60 request
per hour rate-limit.
Go to https://github.com/settings/tokens and create a new token with the
"public_repo" scope.
Then `export GITHUB_AUTH=<your user>:<your token>` and run this script again.
