[bug] aws config not picked up for sso login

[rogue5oul]

Describe the bug
Skyplane init does not autodetect aws config for sso login

To Reproduce

aws sso login --profile [profile name]

skyplane init

Expected behavior
Skyplane is able to pickup existing sso config and not require access key and secret for aws.
My azure login also uses sso and did not present any issues during init.

Environment info (please complete the following information):

• OS: wsl (ubuntu-22.04)
• pipx:1.4.3
• aws-cli:2.13.23
• azure-cli:2.48.1
• Skyplane:0.3.2

I was able to resolve this by exporting my profile

export AWS_PROFILE=[profile name]
