refactor(parser): convert functional tests to unit tests

[leandrodamascena]

Issue number: #2631

Summary

Changes

This pull request aims to enhance the test structure and organization within the parser module.

We've changed functional tests to unit tests, which makes more sense for the type of testing we're doing. Just to explain a little more, these tests specifically test whether given an event, Powertools can parser that and validate the schema.

User experience

There is no change in the user experience.
