matchDescription doesn't check block description on class definition

[Leedehai]

Hi, I found rule jsdoc/match-description is not checking the block description on class definition.

Repro example:

// this doesn't match the regex, but no error was reported
/**
 * blabla
 * @extends Base
 */
class C1 extends Base {
    constructor() {
        super();
        this.a = 1;
    }
}

// this doesn't match the regex either, but no error was reported
/**
 * ?blabla
 * @extends Base
 */
class C2 extends Base {
    constructor() {
        super();
        this.a = 1;
    }
}

// this also doesn't match the regex, but no error was reported
/**
 * blabla
 * @extends Base
 */
const C3 = class extends Base {
    constructor() {
        super();
        this.a = 1;
    }
};

// error reported: JSDoc description does not satisfy the regex
// pattern  jsdoc/match-description
/**
 * aa
 * @param {*} a aaaa
 * @param {*} b aaaa
 */
function foo(a, b) {

}

The .eslintrc config is:

      "jsdoc/match-description": [ "error", {
            "matchDescription": "^([A-Z]|[`\\d_])[\\s\\S]*[.?!`]$",
            "tags": {
                "param": "(|^[A-Za-z][\\s\\S]*$)",
                "returns": "(|^[A-Za-z][\\s\\S]*$)"
            }
        }],

You need to add "contexts": ['ClassExpression', 'ClassDeclaration'] among your options.

Closing as that should resolve, though feel free to comment further as needed.
