[CI] Create .codespellrc; upgrade codespell hook; fix typos

[jbampton]

Description

This PR creates a centralized codespell config.

Some of the benefits of having a separate small .codespellrc will be that less technical contributors will easily see the config file in the repo root and will be able to fix typos.

The new config points users to the ignored words list and shows how to skip files and directories.

Basically this means they won't have to touch the pre-commit config file

This PR upgraded the codespell hook and then fixed some minor typos that the new version of codespell found.
