Add missing region entries to .aws/credentials file`

[LDiazN]

I had an error trying to run an ansible playbook because of a configuration error with AWS, and we solved it by adding the region field in all entries of the credentials file.

Trying to run

./play -i inventory deploy-monitoring.yml -l monitoring.ooni.org --diff --check

I got

You must specify a region. You can also configure your region by running "aws configure".
[WARNING]: Error in vault password file loading (default): Vault password script
/home/luis/Dev/ooni/devops/ansible/password-pipe returned non-zero (253): None
ERROR! Vault password script /home/luis/Dev/ooni/devops/ansible/password-pipe returned non-zero (253): None
(ooni) ➜  ansible git:(password-pipe-aws)

I followed the "run aws configure" advice in the message but it also didn't work.

Adding the region field to every entry in ~/.aws/credentials fixed the problem
