- endpoints.js: replace `\"` with `\\"` in xray response example so the
rendered docs actually show escaped JSON-in-JSON (the original
single-quoted `\"` collapsed to a bare `"` and produced malformed output).
- CodeBlock.vue: drop the unnecessary `\[` inside the regex character
class `[{}\[\]]`; `[` does not need escaping inside `[...]`.
