docs: fix typos

There are some typos in the documentation:

• ourselfes -> ourselves
• simplifiy -> simplify
• corrsponding -> corresponding
• ore -> or
• Customizatons -> Customizations
• stings -> strings
• depreated -> deprecated
• wthout -> without
• argumnt -> argument
• upstrem -> upstream
• reate -> create
• chanages -> changes
• quess -> guess
• reposity -> repository

Fix them via codespell.

Thanks!

Pipeline insisted on a Signed-off-by: but that's not needed for spelling fixes, so merged it anyway. thanks again!
