Improved a11y specs (#17)

* Improve a11y specs for each page is its own spec

* Recorg the _config a bit

* Update .gitignore

* Update lockfile

* Some basic docs

* add badge to README

* update docs

* document RSPEC_CONFIG_FILE= option...

* Add a ruby-version

* bump to ruby 3.2.4

* Add a .tool-versions file

* Add a github codespace

* Add platform for CI

* Run bundle install

* Update .tool-versions to ruby 3.3.0

* Run bundle update

* Run rubocop autocorrect

* Fix rubocop error by adding reason for skipping test

* Install rackup gem, comment out `jekyll_app.compiling?` since the method doesn't exist anymore for some reason

In rack v3 rack/handler is removed and put in a separate gem, rackup: https://stackoverflow.com/questions/75088199/require-cannot-load-such-file-rack-handler-loaderror

NOTE: rack-jekyll gem is archived https://github.com/adaoraul/rack-jekyll/tree/master
Maybe when changing dependency versions the `compiling?` method became lost?

* Add `/` to end of labs, hw, projects permalinks so they are included in accessibility checks

* Add baseurl to site_url so that it loads the site properly in accessibility tests

* Try to fix CI

* Specify rack-jekyll >= 0.5.0 so compiling? method exists

This is probably a temporary fix because rack-jekyll is no longer maintained :(

Should probably look into this instead so we can use newer versions of rack: https://nts.strzibny.name/how-to-test-static-sites-with-rspec-capybara-and-webkit/

* Fix TODO(setup) items in _config.yml

* Fix typos in a11y.md, delete docs/DELETEME

* Rename devocontainer.json to devcontainer.json
