Update requirements.txt to update pydantic minimum version and put py.typed in MANIFEST.in

[Andrew-S-Rosen]

• [] I have added the tests to cover my changes.
• I have updated the documentation and CHANGELOG accordingly.
• I have read the CONTRIBUTING document.

Closes #1765. Essentially, the existing minimum version for Pydantic causes the UI not to render appropriately. Pydantic > 2 is needed now for Covalent. As such, I have set the minimum version to 2.1.1. I chose 2.1.1 intentionally because: a) I tested it and it works; b) FastAPI strictly does not support 2.0.0, 2.0.1, or 2.1.0 so we can't use 2.0 through 2.1.0 anyway.

@arosen93 thanks a lot for identifying the exact cause ! This could have been quite nasty to debug sans UI logs !

@kessler-frost can you take a look at this please 🙏🏻

Upgrading Pydantic might break certain things I believe (hopefully I'm wrong), but let's see what happens. This PR looks gtg from my side.

@kessler-frost: I added the py.typed file to MANIFEST.in as well here. I also don't think the Pydantic version change will be an issue since the test suite likely was already using Pydantic > 2.

Just a heads up to the team Pydantic 2 has been known to not work on AWS Lambda, so keep an eye out for this during the next round of QA

There also is a case where pydantic 2 has been supported only for fastapi versions > 100. So we might need to tweak the fastapi limits in the requirements as well. (Currently <100 also can be installed)

Also when we install fastapi, pydantic gets installed automatically with a fastapi compatible version. So we might need to set both the fastapi and pydantic version correctly to avoid any failures.
