Aws::SQS::Client in GovCloud fails for use of MD5 -> disabled for fips

When using a client from the aws-sqs-sdk on GovCloud environments there is an error generated when trying to produce outbox messages. When the SDK tries to validate the message body using md5s.rb plugin and that generates the following error

`OpenSSL::Digest::DigestError: Digest initialization failed: disabled for fips`

Posting it on this repo since the most similar [issue I could find for the Ruby SDK](https://github.com/aws/aws-sdk-ruby/issues/2397#issuecomment-738200794) repo pointed me here.

This is the stack trace:

```

Are there any configs specific to the client besides the region and queue URL that tell it not to use md5, or is this something missing in the sdk? I haven't been able to find any [other leads here](https://docs.aws.amazon.com/sdk-for-ruby/v2/api/Aws/SQS/Client.html) on this so any pointers are greatly appreciated.
