Adding spellcheck to the CI

[galbash]

Similar to open-telemetry/opentelemetry-python#2878, for the contrib repo

Is your feature request related to a problem?
Yes, would like to ensure spellcheck for the repo

Describe the solution you'd like
I would like codespell to run as part of the CI

Describe alternatives you've considered
None, based it off the fact that the opentelemetry-python repo already uses it
