Bump version for 4.1.1 release (#363)

## Problem

Normally manual version bumps are not needed, but during the 4.1.1
release the final step (git push) failed so the version bump was not
captured in source code.

## Solution

Manually create version bump changes, similar to those seen in past
automated commits. This requires a change to `pyproject.toml` and
`pinecone/__version__`.

## Type of Change

- [x] Bug fix (non-breaking change which fixes an issue)
