Using typos-cli to catch typos + fixes for existing typos

Fix #1929

typos-cli is a tool I have used in the past to automatically catch typos. Feel free to checkout the details here https://github.com/crate-ci/typos

In addition to running this as part of the CI, I do want users the ability to check the typos as well on their local dev setup, so, I provided the just spellcheck. A small note is that we have to install typos-cli. Since this is installed using the cargo, I went ahead to add just dev-prepare where we install the tool using cargo. Since we assume the users should already setup cargo and rust for their dev environment, cargo should make this process OS agnostic. In the future, this recipe can be used to install tools such as cargo-bloat or cargo-udep and etc.

For CI, the github action takes care of setting the cli up and checking.
