Fix spelling in docs

[Jonher937]

I've done my best to map each word to what I think it should say.

There might be some UK <-> US differences that Cspell caught, feel free to edit if something is not to satisfaction.

I have not updated the date in each md since the content has not changed, just the spelling mistakes.

Thank you, @Jonher937, for this contribution; I love it! A bunch of typos that were piling up over the years are now fixed. The documentation should all use the US spelling, but we might have also introduced inconsistencies over time.
Thanks for this!

Could you please sign the commit so we can merge it?
git commit -S

I do not have a gpg keys for git usage and rather strange requirement for a docs repo.
Feel free to amend the commit and edit the author to sign it with an appropriate identity.

Hi @Jonher937 , a SSH key also works for commit signing.

Feel free to amend the commit and edit the author to sign it with an appropriate identity.

Even after adding the key it GitHub, setting up the local git options, executing git commit -S --amend does not sign the commit. It's not worth signing a commit for a docs repo that has no code.

Feel free to export this PR as a diff and commit accoring to your repo rules. I don't need the credit, just don't like typos while reading docs 😃

Hi @Jonher937, this is the sad world of compliance and certifications we live in 😞 ... We have disabled the signing requirement for the documentation. Thanks for your contribution!
