CLI is using the wrong FIPS endpoint for resource groups tagging API

[markdboyd]

Describe the bug

When trying to use the aws resourcegroupstaggingapi service from the CLI with use_fips_endpoint = true in my AWS config, I'm getting this error:

Could not connect to the endpoint URL: "https://tagging-fips.us-gov-west-1.amazonaws.com/"

This error makes sense because indeed that endpoint does not exist. There is no specific FIPS endpoint for the tagging service, so the actual endpoint should be https://tagging.us-gov-west-1.amazonaws.com/.

Somehow the CLI is configured to use the wrong endpoint when running in FIPS mode.
