sysadm/service-urls: Remove scheme in URLs containing brackets

Those URLs makes the ShortenLinkTransform sphinx post-transform from the
pydata theme raise an exception when it attempts to process them using
Python >= 3.11.4, see python/cpython#103848.

So align with other service URLs containing brackets in that doc page
and remove their scheme.
