feat: create json schema for user-input recipe

[nullPointer373]

Issue #, if available:

Description of changes:
I have added a JSON schema file that defines the user-input recipe format and structure. The schema is based on the existing recipe definition in its Java package and its documentation, which allows for further semantic validation.

Why is this change necessary:
The JSON schema is essential for validating user-input recipes and ensuring they conform to the expected format. By using the schema, we can enforce constraints on the recipe properties and catch any potential errors or invalid input early in the process.

How was this change tested:
I have tested the JSON schema by validating it against various recipes manually. And all unit tests (including newly added tests) and integration tests passed successfully.

Any additional information or context required to review the change:
One important aspect to consider is the naming convention for recipe properties. While the recipe follows the CamelCase naming convention for properties in its documentation, hands-on experimentation has revealed that the recipe properties can be case-insensitive when specified. To accommodate this behavior, I have deliberately made all property names in the JSON schema lowercase. During the validation process, the property names will be converted to lowercase in the data object before applying the schema. This approach ensures that the validation process is case-insensitive and can handle variations in property casing.
