TL;DR

Upgraded json-stable-stringify from v1.1.1 to v1.3.0 and removed unnecessary @types/json-stable-stringify dependency.

What changed?

• Upgraded json-stable-stringify from v1.1.1 to v1.3.0 across all packages
• Removed @types/json-stable-stringify dependency as it's no longer needed
• Added null checks when using stringify function by using the nullish coalescing operator (?? '')
• Updated the Element type import in cli-lib/index.ts to remove the unnecessary import
• Updated various BUILD files to remove references to the removed type package

How to test?

1. Run the build process to ensure all packages compile correctly
2. Run tests to verify that JSON stringification still works as expected
3. Verify that the null checks for stringify function calls prevent any potential issues

Why make this change?

The newer version of json-stable-stringify includes its own TypeScript type definitions, making the separate @types package unnecessary. This reduces dependencies and potential type conflicts. The added null checks also improve code robustness by handling edge cases where stringify might return null.
