Backport #32099 by @maantje
This PR addresses the missing `bin` field in Composer metadata, which
currently causes vendor-provided binaries to not be symlinked to
`vendor/bin` during installation.
In the current implementation, running `composer install` does not
publish the binaries, leading to issues where expected binaries are not
available.
By properly declaring the `bin` field, this PR ensures that binaries are
correctly symlinked upon installation, as described in the [Composer
documentation](https://getcomposer.org/doc/articles/vendor-binaries.md).
