Add observer gem to gemspec (#294)

Ruby 3.4 removes the `observer` gem from the standard gems which is why we have the declare the dependency explicitly now. From https://www.ruby-lang.org/en/news/2023/12/25/ruby-3-3-0-released/: > ### Standard library updates > RubyGems and Bundler warn if users do require the following gems without adding them to Gemfile or gemspec. This is because they will become the bundled gems in the future version of Ruby. Fixes #293
