fix: Improve compatibility with standard ethereum tooling

[konstantinabl]

Description:

Currently, our validation process only checks the presence of fields returned by our API, without verifying the format of these fields. This can lead to inconsistencies and potential errors.

Changes introduced:

• Adds separate CI workflow for API conformity
• Pulls the openrpc.json from execution-apis repo in order to validate our response against it

LG, after this we can write some custom tests for the schema. aside from Jeromy comments, i think it looks okay. @Nana-EC has to modify the checks when this is approved in order to be merged.
