Because the dashboard project requires schema verification for plug-ins,
upstreams, etc., and the definition of the schema is written in the Lua
code of Apache APISIX. Therefore, we need a tool to generate a JSON schema
file based on the Lua code of Apache APISIX so that it can be used by the
Go and front-end code of the dashboard project.

If the developer want to sync the JSON schema, he/she should follow this step:

1. export JSON schema file: call apisix export-jsonschema, we will get the file schema.json
2. copy the file schema.json from apisix to the dashboard folder
3. start the dashboard

those steps are much safer. and the dashboard does not need any update.
