feat: generate cli

[boazpoolman]

What does it do?

It adds a new command to the CLI to generate boilerplate code for your plugin.

npx @strapi/sdk-plugin generate

This command will start an interactive CLI where the user can give some input that is used to generate the code. The DX is almost exactly the same as the native strapi generate CLI. The only thing different is the fact that you don't have to select the destination.

This PR basically implements an extension of the @strapi/generators package. Both the file generation and most of the prompts are import from that package and re-used by calling the generate API.

Why is it needed?

The native strapi generate CLI allows for generating boilerplate code for plugins, but that only works for local plugins in the src/plugins directory. For standalone plugins there is no way to generate boilerplate code.

How to test it?

1. Pull this branch
2. Install dependencies: pnpm install
3. Build and push the package: pnpm run build && npx yalc push --publish
4. Navigate to a standalone plugin, or generate a new one with npx @strapi/sdk-plugin init
5. Install the new package in your plugin npx yalc add @strapi/sdk-plugin
6. Run the following command node_modules/.bin/strapi-plugin generate
7. You can now use the interactive CLI and test the different options.

It is always generating javascript even in a typescript plugin because the path is wrong for the way the language detection works in @strapi/generators generate

I think it will need to have a smarter detection where instead of just calling generate() from whatever the cwd is, it should first attempt to cd to the root of the current plugin (essentially look for a strapi plugin package.json and if it doesn't find one cd .. until it does) and then cd into server from there before running generate.

If it detects that it's outside a plugin directory (like if the user tries to run it from their strapi project rather than the plugin dir) then it should probably just log an error that it has to be run from within a plugin dir.

I'm pretty sure we have code for that somewhere in one of the other generation commands that you could look at as an example, but I can't remember where exactly.
