feat: in Strapi project, init creates plugin in plugin path and logs config info

[innerdvations]

What does it do?

When init is run in Strapi project, create plugin in plugin path and log the config info

Why is it needed?

Makes init command more helpful

How to test it?

run init in the root of a Strapi project and it should generate the plugin in the ./src/plugins dir automatically instead of in the root of the project and it should:

• suggest the path you provided as a packageName
• output lines to add to plugins.ts or plugins.js [check that extension is correct]
• have correct plugin config info even when path and packageName are different

run init anywhere else and it should:

• suggest the path you provided as a packageName
• NOT output lines to add to plugins config
