Validate that the source (*.cpp/*.hpp) and markdown (*.md) files within the repo have spell check run on it and are all passing.

@ahsonkhan Is this draft still in progress or can this be closed?

I wanted to see how many and what kind of spelling errors/warnings we have. Let me follow-up on next steps for this PR.

@ahsonkhan, did we get what we wanted from this PR? Can it be closed?

[RickWinter]

@ahsonkhan Can this draft be closed?

[ahsonkhan]

It discovered some issues that were fixed in #4296

And issues like:
#4292

There are a couple other updates needed which I'll update this PR to tackle so we can merge it and get to a complete green state (and we need to figure out why the template CI is intermittently failing).

When you commit, if you go with the PR title as commit message, it probably will be hard to correlate the title with the actual change, so I suggest to commit as something like "Fix typo"
