Remove vcpkg requirement and use conda for range-v3

[horizon-blue]

Motivation

Now that range-v3 is available in conda-forge (conda-forge/staged-recipes#22443), we can simplify the installation and get rid of the need to install vcpkg just to get the range-v3 dependency.

Changes proposed

• Remove vcpkg installation guide from README and CI
• Install range-v3 from conda-forge together when we install Boost and Eigen

Test Plan

I have tested and verify that the changes run on my MacOS machine (with Python 3.10). If the CI also pass then we should be good.

@horizon-blue if there are no other items you want to add to the PR, then let me know if you can do a squash/merge. If not, I think I might be able to fix this for future PRs.
