Exclude JSDoc @extends from 'super()' checks

[ajafff]

This fixes a similar problem as #29244 where JSDoc @extends is treated as class X extends

@ajafff I think this bug needs more discussion; @extends with classes is intended to augment the extends clause of a class. It's only intended for use when type parameters need to be passed:

/** @extends {Array<number>} */
class Numbers extends Array {
}

I think the extends jsdoc should be ignored unless it has a matching extends clause. That would mean a change to getEffectiveBaseTypeNode to only return getJSDocAugmentTag if that tag has a matching extends clause.

Need more discussion of the bug and how to fix it.

@sandersn I think that's different from the changes in this PR.
These checks shouldn't care about JSDoc at all. So it's actually unnecessary to keep using getEffectiveBaseTypeNode for them.

In a follow-up PR getEffectiveBaseTypeNode could be changed to only look at JSDoc if there's an extends clause.

@ajafff you are right, I read the intent of the change backward and now that you added the error on referencing super() in the second test case, it makes sense to me. Thanks!
