use awscli for sso login

Currently sso login command of aws cli is used https://github.com/rcmdnk/boto3-session/blob/3af50cb3899a2f5248a7d96eeef07286a6fbdf63/src/boto3_session/session.py#L64-L67

aws-cli (v2) is python made and it is possible to use the command directly in the python tool.

But currently, only v1 is published in PyPI: awscli · PyPI (1.32.8).

To use v2 as a library, we can install directly from GitHub:

$ pip install git+https://github.com/aws/aws-cli.git@2.15.4

Then, sso login command can be executed by using awscli library:

from awscli.customizations.sso import LoginCommand
from types import SimpleNamespace
import botocore.session
session = botocore.session.Session()
args = SimpleNamespace(no_browser=False, sso_session=None)
sso_login = LoginCommand(session)
sso_login._run_main(args, None)

But awscli v2 does not support python 3.12, yet: V2 support for Python 3.12 · Issue #8342 · aws/aws-cli

Maybe v2 is published in PyPI when 3.12 supports finished (?).

Once awscli v2 becomes available in PyPI, then replace subprocess command to library base command.
