fix: expand JSON Schema scope detection to handle and logical keywords

[Shuklax]

What kind of change does this PR introduce?
Bugfix and Refactoring of the schema scope detection logic.

Issue Number:
Closes #2012

Screenshots/videos:

If relevant, did you update the documentation?
N/A (This change improves the documentation's interactive tools).

Summary
This PR solves a limitation in the JsonEditor where subschemas inside keywords like $defs, definitions, allOf, anyOf, oneOf, and if/then/else were not recognized as interactive "scopes."

The Problem:
Users browsing the documentation (e.g., the Structuring page) could not click on keywords like type or items when they appeared inside a $defs block or a logical combinator. This made the documentation feel disconnected.

The Solution:
I refactored lib/getScopesOfParsedJsonSchema.ts to use a keyword-driven traversal approach. Instead of relying on a restrictive type: object check, it now systematically recurses into Map-based keywords ($defs, properties), Array-based keywords (allOf, anyOf, etc.), and single-subschema keywords (not, if).

Does this PR introduce a breaking change?
No. It is a backwards-compatible improvement to the website's syntax highlighting and interactivity.
