🐛 Update xircuits-components to fetch from local

[MFA-X-AI]

Description

This PR updates the default way xircuits-components fetches the components from pulling each file recursively to simply copying it from the site-packages (this behavior already exists if you run xircuits without xai_components present in your working dir, but it now the default for xircuits-components as well).

If users would still want to fetch the components online or from a specific online branch, they can add the --download tag. This PR also updates several error messages in this process.

Tests

Install Xircuits from this PR's wheel and verify that:

1. when you run xircuits-components, it copies it from site-packages.
2. when you run xircuits-components --download it will download the components from an online source. Verify also that the error messages such as, unable to retrieve xai_components/xai_submodulename cannot be retrieved, skipping... no longer exist in this command.
3. Bonus - if you call xircuits-components --download multiple times in an hour, you will be greeted with the pyGithub error message.
