Replace deprecated option to pypa/gh-action-pypi-publish action

[seifertm]

The PyPI Upload step in the Deploy job of the CI pipeline emits the following warning:

Warning: Input 'packages_dir' has been deprecated with message: The inputs have been normalized to use kebab-case. Use `packages-dir` instead.

The argument should be adjusted accordingly, in order to get rid of the deprecation warning.

I would like to work on it. Just to clarify, should I replace packages_dir with packages-dir line 151 of main.yml?

Based on my current understanding that should be sufficient.
It would be great if you could consult the documentation of the pypa/gh-action-pypi-publish project regarding the deprecation and check if that change is enough.

Based on the information provided in the README and pypa/gh-action-pypi-publish#125, it seems that modifying packages_dir to packages-dir would suffice. Should I create a pull request for this change?

@ujjwal123123 Yes, feel free to proceed. Thanks for double-checking!
