chore(dependency): Bump jsonschema dependency

[javirln]

This pull request updates dependencies in the go.mod file and refactors the iteration logic for schema property validation in fanout.go. The most significant changes include upgrading several libraries, adding new indirect dependencies, and switching to a more robust method for iterating over JSON schema properties.

Dependency updates and additions:

• Upgraded github.com/invopop/jsonschema from v0.7.0 to v0.13.0 for improved JSON schema support.
• Upgraded github.com/mailru/easyjson from v0.7.7 to v0.9.1 for better JSON serialization performance and compatibility.
• Added new indirect dependencies: github.com/bahlo/generic-list-go, github.com/buger/jsonparser, and github.com/wk8/go-ordered-map/v2 to support generic lists, JSON parsing, and ordered maps respectively. [1] [2]

Code refactoring for schema validation:

• Refactored the property iteration logic in generateJSONSchema (in fanout.go) to use an ordered map iterator instead of key enumeration, improving compatibility with updated libraries and ensuring more robust validation against array-based properties.

Dependency removals:

• Removed the indirect dependency github.com/iancoleman/orderedmap in favor of github.com/wk8/go-ordered-map/v2, streamlining ordered map usage.
