Maintenance: remove aws-sdk/util-dynamodb dependency in favour of commons package

[am29d]

Summary

In #3442 we missed to add @aws-sdk/util-dynamodb package to peerDependenciesMeta as option, which now pulls the dependency for some package managers like pnpm.

Remove util-dynamodb dependency since we have implemented the unmarshall function in our commons package.

Why is this needed?

Because we have moved the implementation of unmarshall function to commons package.

Which area does this relate to?

Parser

Solution

Add commons dependency to parser utility.

I think we should add the custom function we added in #3482 and remove the dependency altogether instead.

The function is present in the commons package and is already being used by the DynamoDB schema.

I agree, will adjust the title and description, as well the PR.
