feat(ci): add 'typos' check

[woshilapin]

resolves #311

Description

Will catch most of the typos in the documentation and markdown files automatically in CI (see #311 for details). Note that I chose to not create a new job and make it part of the check job (but I can go either way).

Also, I configured typos to ignore a bunch of 7-chars commit hash and one of your other project halp (which obviously is a typo of help 🙃).

Motivation and Context

See #311.

How Has This Been Tested?

CI will tell.
