Add aarch64-linux to list of Gemfile platforms

[colby-swandale]

I use Dev Containers on my MacBook which recently has stopped working due to:

Tailwindcss::Commands::ExecutableNotFoundException: Cannot find the tailwindcss executable for aarch64-linux in /workspaces/rubygems.org/.bundle/ruby/3.3.0/gems/tailwindcss-rails-2.7.7/exe (Tailwindcss::Commands::ExecutableNotFoundException)

If you're using bundler, please make sure you're on the latest bundler version:

    gem install bundler
    bundle update --bundler

Then make sure your lock file includes this platform by running:

    bundle lock --add-platform aarch64-linux
    bundle install

This Pull Request adds the aarch64-linux platform to the Gemfile.lock
