Default credentials provider chain documentation doesn't look right

[liwadman]

Describe the issue

The default search list doesn't look right based on the botocore code I reviewed, and doesn't quite make sense. e.g. the sso provider would only be brought in if a profile in any location used an sso profile, and the sdk wouldn't do a specific search on existing config files for sso providers. As well the assume role provider is the implimentation of the config files e.g. the assume role provider is what's used with the relevant settings of a config file and the default profile within it.
