update jspark download location

As per https://github.com/geopython/GeoHealthCheck/pull/446#issuecomment-1595283162

CI continues to error out based on this dependency download. @justb4 perhaps we can just include as part of the source code (stable)?

[justb4]

Yes. Relying on a personal URL seems brittle.

[justb4]

Though it could be a HTTP/2 problem, some kind of negotiation mismatch which urlopen() can't handle. Seen this with MapServer WFS from pygeoapi as well: https://lists.osgeo.org/pipermail/mapserver-users/2023-March/083084.html

See e.g.

>>> import urllib.request
>>> urllib.request.urlopen('http://python.org/')
<http.client.HTTPResponse object at 0x104960a58>
>>> urllib.request.urlopen('https://johnresig.com/files/jspark.js')
Traceback (most recent call last):

    raise HTTPError(req.full_url, code, msg, hdrs, fp)
urllib.error.HTTPError: HTTP Error 403: Forbidden

[justb4]

Problem of the 403 here is not sending a UserAgent HTTP header. This works:

url='https://johnresig.com/files/jspark.js'
request_site = Request(url, headers={"User-Agent": "Mozilla/5.0"})
urlopen(request_site).read() 

[justb4]

Still for this case placing jspark.js directly under static/lib is better option. Most other URL fetches are GitHub and CDNs, thus more stable. We did a similar thing with JQuery UI.
