This PR converts the `frameworks.json` file to TypeScript, and extends the values with the detection logic from `@vercel/static-build`, so that it's publicly editable. You also don't need to do the type casting downstream anymore.
As a consequence, it also makes Zola a 1st-class framework, as it was previously missing from the `frameworks.json` file, but present in the static-build frameworks. An example has been included based on their "Getting Started" tutorial.
