Change GitHub Actions workflow Ruby matrix

We can drop Ruby 2.4 from our test run matrix. It is beyond EOL.
Let's add 2.7 instead.

+# There's an issue in 1.12.5 that causes XHTML elements to be generated badly,
+# causing Gollum's test suite to fail.[1] The issue has been fixed upstream,
+# but we're still waiting for a new Nokogiri point release.
+#
+# However, 1.12.5 is a security patch, so we don't want end users to use an
+# older version of Nokogiri. But this is safe to do in our CI environment.
+#
+# Once there's a new Nokogiri release, we can remove this dependency and JRuby
+# CI should pass normally again.
+#
+# Note that Nokogiri 1.11+ does not support Ruby v2.4.x anymore. So to make our
+# current CI workflows pass, we should only try to install this version of
+# Nokogiri for newer Ruby versions.
