fix: Fix publish-pypi

[hiohiohio]

Context:

• introduced poetry-dynamic-versioning in https://github.com/alpacahq/alpaca-py/pull/390
• however, it causes an error when installing the poetry-dynamic-versioning package as pipx does not support installing multiple packages

  pipx install poetry poetry-dynamic-versioning
  shell: /usr/bin/bash -e {0}
usage: pipx [-h] [--version]
            {install,uninject,inject,upgrade,upgrade-all,uninstall,uninstall-all,reinstall,reinstall-all,list,run,runpip,ensurepath,environment,completions}
            ...
pipx: error: unrecognized arguments: poetry-dynamic-versioning
Error: Process completed with exit code 2.

Changes:

• separate installing poetry-dynamic-versioning for poetry-publish

Wondering if the versioning will still be published here -> https://github.com/alpacahq/alpaca-py/blob/ba83efb4660c0aabb0ffa54732ef79fe04785747/alpaca/common/rest.py#L145

The __version__ is from here and the version number will be replaced by poetry-dynamic-versioning if all configuration is good. https://github.com/alpacahq/alpaca-py/blob/ba83efb4660c0aabb0ffa54732ef79fe04785747/alpaca/__init__.py#L2C8-L2C8
