Publish nightly versions of Ruby gems every day

Creates new workflow that automatically publishes nightly versions of
Ruby gems (selenium-devtools, selenium-webdriver) to GitHub Packages.

Every nightly package is versioned in the following manner: <current-version>.nightly.<YYYmmdd>

Installation via Bundler can done by adding following to Gemfile:
  source "https://rubygems.pkg.github.com/seleniumhq" do
    gem "selenium-webdriver", "~> 4.6.1.pre" # replace 4.6.1 with the latest version
  end
Then running:
  BUNDLE_RUBYGEMS__PKG__GITHUB__COM="USERNAME:TOKEN" bundle install

Installation via RubyGems can done by running:
  gem install selenium-webdriver --pre --clear-sources --source "https://USERNAME:TOKEN@rubygems.pkg.github.com/seleniumhq"

For more details on authentication and installation from GitHub
Packages, check out https://docs.github.com/en/packages/working-with-a-github-packages-registry/working-with-the-rubygems-registry#installing-a-package.

To publish manually, run the following Bazel targets:
  bazel run rb:webdriver-bump-nightly-version
  GEM_HOST_API_KEY="Bearer TOKEN" bazel run rb:selenium-webdriver-release-nightly
Replace `webdriver` with `devtools` to publish selenium-devtools.
