Insert a proper flipper-plugin version

Summary:
`flipper-pkg init` would always introduce `flipper-plugin` peer with version `latest`. Since that can never be checked against the current flipper version, it always generated a warning. Updated the init process to take the version the plugin was generated with as base version instead.

Note that in the test the version will always display as 0.0.0, will double check after release that the proper version will show up when running from npx, but don't see a reason why not (famous last words)
