provide OpenApi metadata

[nimo23]

What is the problem this feature would solve?

Currently, it is not possible to access OpenApi (meta)data within userland source files with kubb. For example, in orval I can use something like that to make use of the openapi metadata:

// write a jsdoc with OpenAPI metadata in each generated file
header: (info: InfoObject): string[] => [
    `Generated from orval.`,
    `Do not edit manually.`,
    ...(info.title ? [info.title] : []),
    ...(info.description ? [info.description] : []),
    ...(info.version ? [`OpenAPI spec version: ${info.version}`] : []),
],

which returns:

/**
 * Generated by orval.
 * Do not edit manually.
 * TaskApp API
 * OpenAPI spec version: 1.0.0
 */

An equivalent in Kubb could be achived with the help of https://github.com/readmeio/oas:

pluginClient({
    output: {
         // access openapi metadata to add it to the banner
         banner: ...
}}
