Feature/add gov cloud to ssm

[maxhoheiser]

This PR adds the SSM AWS Linux resources available in two not publicly available gov cloud regions - us-gov-east-1 and us-gov-west-1.

The data was provided by a customer who preferred not to share the original AMI values; hence, these values are randomly generated and differ from the official AWS values.

This PR was originally proposed to moto origin, but due to automatic update concerns not accepted: getmoto#8006

Thanks for adding this @maxhoheiser. We can keep this here until we can find a way to automate it upstream.

Could you add a small sanity test to verify that these values can be retrieved for the GovCloud partitions within SSM?

If we want to get it in today in the support week, I am not able to add the test. Maybee I have time next week.

Thanks for adding this 💯

Unless this is required to go in v3.7, I'll bump Moto-Ext sometime next week
