Previously the `bin` directory would only be added to `PATH` if it existed (due to it being set by `lifecycle`), which is only the case if one of the installed dependencies has an entry point script, which causes Pip to create the `bin` directory and place a wrapper script inside it for that package's CLI command. This meant: 1. We had to suppress Pip's warning during install (since Pip isn't to know that the `PATH` will be correctly set later) 2. If an app has no dependencies with an entry-point (so the app image doesn't have a `bin` directory), then at run-time tries to pip install a new package that does have an entry point (eg when debugging), then that new script won't be on `PATH`. As such, we now add the `bin` directory to PATH explicitly, instead of relying on `lifecycle` automatic addition.
