Add script `packages/mermaid/scripts/create-types-from-json-schema.mts`
to automatically generate the TypeScript definition for `MermaidConfig`
from the `MermaidConfig` JSON Schema at
`packages/mermaid/src/schemas/config.schema.yaml`.
To do this, we are using this library
[`json-schema-to-typescript`][1], which is also used by Webpack to
generate their types from their JSON Schema.
In order to make sure that this isn't a breaking change, the script
makes all fields **optional**, as that is what the original typescript
file has.
Additionally, I've put in some custom logic into the script, so that
the exact same order is used for the TypeScript file, to make the
`git diff` easier to review. In the future, we can remove this custom
logic, once we no longer need to worry about `git merge` conflicts.
