What MediaWiki version was MediaWiki\ResourceLoader\ResourceLoader added in?

I confirmed it is in MW 1.39. This extension still supports MW 1.35 on master, but I think it's high time to drop that, so no issue with merging the PR as is.

@JLTRY please sort the use statements

It's cool you are paying attention, but I disagree that sorting imports is important. They are hidden by modern tools by default and can easily be auto sorted. Amending a PR to fix a sort does not seem like a good use of someones time.

Thank you @JLTRY, it is all fine now: all the tests pass. Your contributions are welcome. 😊

Thanks for the fix. I just tested SemanticResultFormats master and the datatables format is fixed, it works but the jqplot format still gives Error: Class "ResourceLoader" not found I am happy to do some tests or send info if needed, so please let me know.
