removing duplicate module validation caught by cfn-lint

[PatMyron]

https://github.com/aws-cloudformation/cloudformation-cli/pull/634 https://github.com/aws-cloudformation/cloudformation-cli/pull/644

left module-specific validation like restrictions on exports, macros/transforms, and nested stacks

[miparnisari]

The fragments folder cannot have more than 1 json or yaml file. Can we add this validation? Otherwise it'll fail at runtime during registration

That validation should already exist, Maria. I had added that a while ago.

~I was able to submit a module today with two files inside fragments: s3.json and blabla.json.old~

I had an old version of the CFN CLI

@MalikAtalla-AWS @PatMyron does this change still apply and/or what rework is needed here?

My comments are addressed, but the build is failing @mircealam

looks like that test was removed in https://github.com/aws-cloudformation/cloudformation-cli/pull/1028 already
