Describe the bug
The function _get_package_config is called several times under normal operation of the reflex run publish command. The _get_package_config makes an IO call to load the pyproject.toml file. While not a huge issue, this is unnecessary to reload the file multiple times.

To Reproduce
Steps to reproduce the behavior:

• Code/Link to Repo: https://github.com/reflex-dev/reflex/blob/main/reflex/custom_components/custom_components.py#L73
• To recreate:
• Add a debug statement in _get_package_config
• Run run reflex component publish -u saf -p asdf
• Notice how many times this function is called.

Expected behavior
Typically, you only want to load a configuration file once and use the results. Or alternatively cache the results for future reference.
