Capybara with selenium fails on ruby 2.7.6

Having reverted the ruby back to 2.7.6 to get the environment built on morph.io, it now breaks at

REGISTER_FORM_URL = 'https://online.whittlesea.vic.gov.au/s/publicregister'
capybara = Capybara::Session.new(:selenium_chrome_headless)
# error on following line:
capybara.visit(REGISTER_FORM_URL)

when the main branch is reset to ruby_2_7_6 branch of the ianheggie-oaf/city_of_whittlesea_aura_planning_register scraper. Note: ruby 2.7.6 appears to be the latest ruby that can be built - see https://github.com/openaustralia/morph/issues/1336 for ruby 3.1.6 issue.

          **********************
          The public API of some Rubyzip classes has been modernized to use named
          parameters for optional arguments. Please check your usage of the
          following classes:
          * `Zip::File`
          * `Zip::Entry`
          * `Zip::InputStream`
          * `Zip::OutputStream`
          Please ensure that your Gemfiles and .gemspecs are suitably restrictive
          to avoid an unexpected breakage when 3.0 is released (e.g. ~> 2.3.0).
          See https://github.com/rubyzip/rubyzip for details. The Changelog also
          lists other enhancements and bugfixes that have been implemented since
          version 2.3.0.
