Previously, the following MDX could not be parsed by lexical:
```tsx
<RestExamples
data={[
{
operation: "Find"
}
]}
```
Instead, it had to be converted into valid JSON:
```tsx
<RestExamples
data={[
{
"operation": "Find"
}
]}
```
This PR permits using the first example, as it swaps out JSON.parse with
them ore lenient [json5](https://www.npmjs.com/package/json5) package
