`warnings.simplefilter` does not validate that the category passed in is actually a class. This means that an invalid category leads to a `TypeError` whenever a warning would otherwise occur due to `issubclass` check failing.

It is a very small thing, but for usability it would be clearer if this was checked right away.

Here is the patch to add the validation in simplefilter with the test.

Here's a patch that uses the same approach as in issue 16382.

@Bonifacio2, As commented on the PR, I think opening a PR with a patch close to what @berker.peksag suggested looks more elaborate, IMHO.

Thanks for your contribution.

I have submitted the path by @berker.peksag with one additional test case in a new PR.

@nanjekyejoannah I saw you responded to the other PR, but that died down. Would you mind taking a look at mine? I'm happy to help land this :)
