Initialization doesn't like provided SSO start url

[swirle13]

Output of aws-sso version:

AWS SSO CLI Version 2.0.3 -- Copyright 2021-2025 Aaron Turner

Describe the bug:
When initializing aws-sso-cli via aws-sso, pasting in the SSO start URL value as copied directly from the AWS Access Portal, it fails to parse the value. URL is in format of https://a-bcdef12345.awsapps.com/start/#. Only when deleting https:// does it accept the value.

To Reproduce:

1. aws-sso
2. Copy SSO start URL from AWS Access Portal, looks like https://a-bcdef12345.awsapps.com/start/#
3. Response of ERROR unable to resolve host=https://a-bcdef12345.awsapps.com/start/#

Note: You do not need to redact AWS AccountIDs from outputs or config.
Per Amazon,
"While account IDs, like any identifying information, should be
used and shared carefully, they are not considered secret,
sensitive, or confidential information."

Expected behavior:
Allow parsing of URL as provided by AWS.

Screenshots:

Desktop (please complete the following information):

• OS: Debian GNU/Linux (dev container)
• Version: 12.10 (bookworm)

Additional context:
I would think the program would accept the value as copied directly from the access portal. Seems a bit cumbersome to have to change the value. I would think it would accept and remove the scheme, delimiter, and double slash, https:// from the value provided.

Contents of ~/.aws-sso/config.yaml:

No such file or directory

Definitely not a bug since it requests the hostname (and provides the example input of XXXXX.awsapps.com).
