fix: correct typos

[setchy]

A few typo corrections

In other projects I've set up the typos tool, and run it in CI. It's pretty simple:

      - name: Check spelling
        uses: crate-ci/typos@master

Is that worth doing on this project too?

might be overkill for where we're at atm. I only found these three. if we continue to detect them, then yes, i'd agree
