--stdout flag not working since updating to MacOS 13.0 (22A380) (Ventura)

[Daemeron]

Yesterday I have updated to the latest MacOS version and today I noticed trying to login through non default browser by utilising --stdout flag does not appear to work anymore. It looks as if that flag is ignored and aws-vault proceeds to opening the login url with default browser.

• I am using the latest release of AWS Vault

Running v6.6.0

• I have provided my .aws/config (redacted if necessary)

[default]
region=eu-west-1
output=json

[profile project-a]
sso_start_url=https://xxx.awsapps.com/start
sso_region=eu-west-1
sso_account_id=xxxxxx
sso_role_name=AWSAdministratorAccess
region=eu-west-1
output=json

[profile project-b]
sso_start_url=https://xxx.awsapps.com/start
sso_region=eu-west-1
sso_account_id=xxxxx
sso_role_name=AWSAdministratorAccess
region=eu-west-1
output=json

• I have provided the debug output using aws-vault --debug (redacted if necessary)

aws-vault login --stdout --debug project-a                                                                                                                             ~

Hi, I have realised I must have misinterpreted my problem. It would appear that fresh login requires browser interaction no matter what, and the --stdout comes in action after that has been done to output the resulting url.

I am not entirely sure whenever my expectation on how --stdout should work is unreasonable, but I expected that aws-vault would not interact with browser directly.

Either-way, I was trying to use a --stdout to circumvent inability to tell aws-vault which browser to use. I personally use different browsers for work and personal needs, so being able to pick which one I want aws-vault to use would be a godsend. There appear to be a issue asking kindly for just that already (#959). Thus, I will close this issue.
