The cache is no longer generated at runtime when the application runs -
which may take quite a while, especially on fresh installations.
A `components.json.gz` file is instead generated by the CI/CD process on
every commit to the main branch, and distributed with the package.
The application will read this file when the `inspect` plugin is first
initialized.
This also means that we can no longer cache the `install_cmds`, as they
change depending on the target OS. A new
`application.get_install_commands` action has now been made available to
the UI, so it can get the correct installation commands at runtime.
