Add link or example code to set regional endpoint to STS / Client / assume_root

[lmaeffw]

Describe the issue

Looking at the API information page of [STS] / Client / assume_root
It requires more in depth search flipping through links to complete the prerequisite of setting regional endpoint for users to use the API AssumeRoot. Within the Note that warns "The global endpoint is not supported for AssumeRoot" can we add a link that directs [2] Manage AWS STS in an AWS Region - Writing code to use AWS STS Regions.
Customer enquired to add documentation for easier visibility as well as the code they had to write to enable regional endpoint from the following:
os.environ['AWS_STS_REGIONAL_ENDPOINTS'] = 'regional'

Thanks for reaching out. User Guide pages like the one you referenced must be updated directly by service team doc writers. You can use the Provide feedback links at the bottom of those pages to send feedback to the appropriate team.

For Boto3 this is documented here: https://boto3.amazonaws.com/v1/documentation/api/latest/guide/configuration.html

Is that sufficient or did you think more should be added? For Boto3 code examples specifically maybe something could be added here: https://boto3.amazonaws.com/v1/documentation/api/latest/guide/examples.html.
