[Meta] Refactor Rule Formatter

## Parent Epic (If Applicable)

https://github.com/elastic/ia-trade-team/issues/810

## Meta Summary

The formatter was once written when the schemas were flat structures. Now that they have evolved to nested structures, the rule formatter should be refactored.
- The new solution should easily be able to specify the order of the toml file.
- The solution should remain consistent and not unintentionally create new sha256 calculations.
- The solution should still support some of the old features:
- text wrapping after a certain character limit
- skipping fields that should not be formatted or normalized
