Concrete example of using standalone at runtime

**What version of Ajv you are you using?**
8.8.2

**What problem do you want to solve?**
I do not know how to use the `validate_schema.js` at runtime to validate the schema? The https://ajv.js.org/standalone.html

**What do you think is the correct solution to problem?**
Update the docs or create an example somewhere that clearly distinguishes between generating the JS files and consuming them for validation.

**Will you be able to implement it?**
Maybe if someone can give me a rough example?
