Outdated Installation Instructions for Ubuntu 19.10

[gardon]

Ruby 2.5 is available and the PPA in instructions is failing. Just replacing it with ruby2.5 and ruby2.5-dev packages without any ppa seems to be enough.

[cleaver]

Everything should now be working on 2.7 by default.

ubuntu install still seems very untested.

Sent a PR in for docs to make install work without error, but even after this good install don't get a sitediff script/binary:

$ export GEM_HOME="$HOME/.gem" # this is the fix for devs-but-not-ruby/gem users
$ gem install sitediff

a little bit skeptical this is going to be much more than just regular diff of two sites, but figured it was worth a whirl if it worked. but doesn't seem to.

Closing issue as SiteDiff is updated to Ruby 3.1.2.
