BREAKING: Update jsdoc/require-jsdoc to require documentation for more things

[Mrtenz]

This updates the jsdoc/require-jsdoc rule to require documentation for:

• Arrow functions.

  const myFunction = () => {
    // ...
  };

• Class declarations.

  class MyClass {
    // ...
  }

• TypeScript enum declarations.

  enum MyEnum {
    // ...
  };

• Function expressions.

  const myFunction = function () {
    // ...
  };

• TypeScript interface declarations.

  interface MyInterface {
    // ...
  };

• Method definitions.

  const myObject = {
    myFunction() {
      // ...
    },
  };

• TypeScript type alias declarations.

  type MyType = {
    // ...
  };

• TypeScript property signatures.

  type MyType = {
    myProperty: string;
  };

Breaking changes

Each of the code blocks above was previously valid, but will now produce an error.

Closes #223.
