ci: Add spell checker in pre-commit

[vedpawar2254]

Fixes #2971

I added a spell checker to the pre-commit, please test it out and see if it's good, i can update if needed.
Also there are a few spelling mistakes that this is giving me, I'll fix them and raise a pr in a bit
Thanks

It's not clear to me if this actually addresses #2971 because our current spell checker runs on every word and this seems like it's got more of a typo-specific thing going on, but it seems like it could be a good supplement nonetheless.

Yeah I guess you are right, I tried with check-spelling but seems to have some docker thing and meanwhile I came across this and thought it would't hurt.
I am still not sure how to do the check-spelling one though if could help me out a little there that would nice.

Alas, I don't know any obvious alternatives, so it's a research project for someone!

Anyhow, this looks like codespell is not failing when we run it, so it's probably safe to try it out on main and see if we find it helpful. Before I merge this, can you put a few lines explaining it into https://github.com/intel/cve-bin-tool/blob/main/CONTRIBUTING.md#running-linters -- just a line explaining what it's for and then a little section explaining how to run it on the command line so people can cut/paste if they want to run it before pre-commit triggers. You can see what the other ones look like there.

I guess this should be good

Minor nit with explicitly setting the version number in requirements.txt, but I'll accept my own suggestion and then merge this once the tests are done. Thank you again for your time researching and setting this up!
