Closes#35256
This PR fixes a bunch of typos in docs files.
I ran codespell on `*.adoc` and `*.md` files in the repo in interactive mode
carefully checking each identified typo and proposed fix for false positives.
The most widely read file with typos identified is likely the changelog/migration guide.
