This adds testing on Node.js 17 in addition to the currently tested 10, 12, 14
and 16 versions.
Also, update Grunt & `karma-*` packages.
Testing in Karma on jsdom is broken in Node 17 at the moment; until we find
a fix, this change disables such testing on Node 17 or newer.
Node smoke tests & promises aplus tests are disabled on Node.js 10 as they
depend on jsdom and the latest jsdom version doesn't run properly on Node 10.

The EasyCLA status check is required so this won't get missed. The old JSF CLA
is dead, the provided link doesn't return meaningful information. There's no
good replacement link for the old CLA; PR authors are just supposed to sign the
new CLA by clicking on a link posted by the EasyCLA bot when they submit their
first PR since EasyCLA was enabled for the repo.

The issue about selectors with '#' being broken is old and no longer
frequently reported so this commit removes it from the list. On the other
hand, we're now getting lots of reports about the security fix in jQuery 3.5.0
that was also a breaking change: gh-4642. This one is now mentioned in the
list.
Closes gh-4728

JSFiddle doesn't support IE (even 11) anymore so we shouldn't advise users
to use it to create test cases. To make people have a choice, add CodePen
to the list.
Also, link to specific starter templates so that novices don't need to spend
time thinking how to set up the basic structure.
Closes gh-4289
We no longer support jQuery 1.x/2.x and mentioning 3.x would just mean the text
gets out of date once we release jQuery 4. We only really support the latest
jQuery version so let's make that clear.
Closes gh-3372
