fix(linter): Fix casing for unicorn/explicit-length-check config option. (#16269)

[The original rule](https://github.com/sindresorhus/eslint-plugin-unicorn/blob/main/docs/rules/explicit-length-check.md) has it cased as `non-zero` but we were using camelCase `nonZero`. This change fixes the config option docs and also ensures that rules are deserialized more simply.
