docs(linter): add prettier-ignore where formatting ruins code (#8978)

While running `just website`, I noticed that these docs were causing some issues when running `npm run fmt` subsequently, I think due to the usage of character escapes. Disabling prettier seems to stop this from occurring.

Also the code examples in `no-nonoctal-decimal-escape` had weird formatting due to the usage of text which gets parsed as a label, so I updated the example.
