chore(spell-check): add tool names to spelling allowlist

[Shrishti1701]

Adds commonly used tool names like codecov, Codecov, and Dependabot to the spell check allowlist in .spelling/expect.txt.

This resolves false positives in the check-spelling workflow that were flagging these valid names as spelling errors.

Fixes #5044.

I'm going to update your branch since I had to merge that test fix PR earlier today.

Oh, but I just realized: you've added words but the error was actually complaining that we had words that were no longer needed:

aiohttp cdx cwes getbootstrap GMS NOTKNOWN pyyaml rdf skontar spdx Svunknown urllib

are the ones it's recommending we remove.

See the "check spelling report" comment on #5042

[Shrishti1701]

@terriko I've removed the words flagged as unnecessary in the spell-check report. Let me know if anything else needs to be updated!

[terriko]

One more request: looks like you've got the added terms in the wrong file. Can you merge those into .github/actions/spelling/expect.txt so this can be merged?

[Shrishti1701]

Sure I'll do it right away.
And apologies for the confusion.

[terriko]

I think whatever you did made it worse? We want all the changes in .github/actions/spelling/allow.txt (not expect.txt) so that should be the only file in this PR when it's ready.

Also, it's clear that you're really having some trouble with git. I'm not sure if it's because you're using a tool that's steering you wrong on how to make a pull request, but there are a number of tutorials out there and it might be worth spending some time following one if you're intending to do more software development. I recommend looking for a tutorial written before 2020 if you can -- there's been a lot of AI spam in this area but there used to be lots of good blog posts and stuff explaining how to fix pull requests.

@terriko Hi terriko,
I'm really sorry for the confusion and for making the pull request more complicated than it needed to be. I'm still learning Git and the proper workflow, and I really appreciate your patience and clear feedback. I'll fix the pull request so that only .github/actions/spelling/allow.txt is changed as you asked.
I genuinely want to grow as a developer, and I’ll make sure to study more about Git and pull requests to improve. Thank you again for taking the time to help me!
