[emanor-okta]

This PR adds the ability to source multiple AWS Fed App Ids in the okta.yaml configuration file.

I'm going to close this one, I think equivalent behavior is in the v2.1.0 release

https://github.com/okta/okta-aws-cli?tab=readme-ov-file#configuration-by-profile-name

Configuration by profile name

Multiple okta-aws-cli configurations can be saved in the $HOME/.okta/okta.yaml
file and are keyed by AWS profile name in the awscli.profiles section. This
allows the operator to save many okta-aws-cli configurations in the okta.yaml.

$ okta-aws-cli web --profile staging

Example $HOME/.okta/okta.yaml
