chore(build): add spellchecker github action

Add a GitHub workflow that can detect spell errors and report on the PR.

This commit also includes the fixes for the initial errors reported by this tool.

To verify this locally prior to commit:

Install cspell. npm install -g cspell
From the root directory. Run the command: cspell --config ./cSpell.json "**/*.md"

Sometimes the tool will display some valid words as errors since they are not part of a standard dictionary. You can customize the tool by adding the new words can be added to one of the following files:

hack/cspell-contributors.txt - company and user names
hack/cspell-ignore.txt - random text that is part of code output
hack/cspell-words.txt - technology words
