testinfra: Update selenium calls
Now that all the bridge nodes are Jammy (3.10), we can uncap this
dependency which will bring in the latest selenium.  Unfortunately
after investigation the easier way to do things I hoped this would
allow doesn't work; comments are added and small updates for new API.

Update the users file-match so they run too.

# NOTE(ianw) This is a mash-up of things I found on
# stackoverflow and other bits googling "full size
# screenshot". You expand the viewport and take a
# shot of the <body> element so that you don't also
# get scrollbars in the shot, with some tweaking
# because of the window size.
#
# Update 2022-20-09 : The Firefox driver with Selenium 4
# has a very simple get_full_page_screenshot_as_png()
# which would be perfect -- but -- this only works when
# using the local Firefox connection, not the remote
# connection we are using here to talk to the docker
# container. I looked at switching this, but to talk to
# the local firefox you need geckodriver -- and that
# doesn't work with Ubuntu Jammy because Firefox is now
# distributed as a snap, not a regular package, and it
# doesn't work together [1] (apparently you can get around
# it, but it's just other hacks [2]). So we still have
# this ...
