Fly fails to include the appropriate release config for my Phoenix app because it detects it as being < 1.7.9 when it's actually 1.7.10

Please only report specific issues with flyctl behavior. Anything like a support request for your application should go to https://community.fly.io. More people watch that space and can help you faster!

Describe the bug Upon launching a Fly app based on an existing Elixir/Phoenix configuration, Fly states "We recommend upgrading to Phoenix 1.7.9 which includes a release configuration for Docker-based deployment." Unfortunately, I double-checked and my Phoenix version was 1.7.10, which in semver is actually greater than 1.7.9, but which a naïve comparison might detect as less than.

We recommend upgrading to Phoenix 1.7.9 which includes a release configuration for Docker-based deployment.

If you do upgrade, you can run 'fly launch' again to get the required deployment setup.

If you don't want to upgrade, you'll need to add a few files and configuration options manually.
We've placed a Dockerfile compatible with other Phoenix 1.6 apps in this directory. See
https://hexdocs.pm/phoenix/fly.html for details, including instructions for setting up
a Postgres database.

bash> cat mix.exs | grep phoenix
      {:phoenix, "~> 1.7.10"},
      {:phoenix_ecto, "~> 4.4"},
      {:phoenix_html, "~> 3.3"},
      {:phoenix_live_reload, "~> 1.2", only: :dev},
      {:phoenix_live_view, "~> 0.20.1"},
      {:phoenix_live_dashboard, "~> 0.8.3"},

Note: In addition, I noticed while troubleshooting this that Fly's operations do not respond to control-C/SIGINT (such as after accidental command activation).
