[Documentation]: TypeScript 4.9 documentation

[jonniebigodes]

Describe the problem

Per #30353, TypeScript 4.9 will be the default TypeScript version used in the examples and documentation. The documentation should reflect the new syntax and features introduced in TypeScript 4.9 (e.g., satisfies).

What needs to happen:

• Vet the examples and remove the old TypeScript variants in favor of the new TS 4.9 syntax
• Verify that the Angular and Web Components support the new TS 4.9 syntax
  • Based on the above, vet the documentation and remove any conditional rendering of the documentation
