feat: add bacon hosting integration

[Odonno]

I often, if not always, use bacon to run a Rust app in Aspire. Bacon is the best solution to run background jobs for Rust apps.

Part of #1048

PR Checklist

• Based off latest main branch of toolkit
• PR doesn't include merge commits (always rebase on top of our main, if needed)
• New integration
  • Docs are written
  • Added description of major feature to project description for NuGet package (4000 total character limit, so don't push entire description over that)
• Tests for the changes have been added (for bug fixes / features) (if applicable)
• Contains NO breaking changes
• Every new API (including internal ones) has full XML docs
• Code follows all style conventions

Other information

Note: on how bacon works, the default command run if none provided is bacon check, equivalent to cargo check. It has no interest to run check by default for an Aspire resource. That's why I made it consistent with AddRustApp to use run command by default. But the main difference is that I allow any command override (not just run <args>), in order to allow additional tasks like check, clippy, test, etc..

Question: I would want to do the same for AddRustApp but that introduce a breaking change. One would want to have a "test" run for example.

For information, the default solution cargo-watch is no longer maintained and Bacon is one of the recommended solution.
