[Feature] Support Python 3.13

[deeleeramone]

This PR adds support across all packages and dependencies for Python 3.13.

Additionally, it moves the openbb folder to inside the core package and updates the references to these folders. This ensures that the build script ships when only openbb-core is installed.

I have not yet encountered anything requiring syntax modifications, and bumped package versions are still compatible with 3.9.

Testing done:

• Complete test suite.
• Manual inspection of an empty installation build, and then adding custom extensions + creating/watching for errors in the openbb-build process.

Hey, the 3.13 part looks good. I would like to ask for the rationale to move the built python interfaces from openbb to openbb_core. This technically doesn't de-bloat the package, but instead actually introduces more "dead code" to the core for those who operate minimalist deployments or custom extensions.

This technically doesn't de-bloat the package, but instead actually introduces more "dead code" to the core for those who operate minimalist deployments or custom extensions.

The rationale is that the build script not being part of openbb-core has resulted in the need to employ other workarounds.

I'm not sure if "dead code" is the correct analogy, if one was just utilizing the Python interface, all of the API interface code is essentially "dead code". If it ships with no static assets, then those files will only get populated if, and when, the Python interface is imported or built.

One feature of openbb-core is supporting both Python and API interfaces out-of-the-box. Therefore, the build script and basic import logic should be, in my opinion, be part of the core package.

If you disagree, or want to reserve judgement for later, we can scope it out. Just feels like a decent time to make this kind of move.
