Add plugin package name

Clear and concise description of the problem

Currently, it is not obvious which plugin originated from which package. It would be helpful to show that information.

Suggested solution

Recommend plugins to add api.devtools.package values:

const p = {
  name: 'foo',
  api: {
    devtools: {
      package: '@vitejs/plugin-vue'
    }
  }
}

and make devtools will read that information.

We can also add description property to show it.

Validations

• Follow our Code of Conduct
• Read the Contributing Guide.
• Check that there isn't already an issue that request the same feature to avoid creating a duplicate.

Start by locating the code that reads plugin metadata and renders recommended plugins in the Vite devtools repository. Trace how the proposed api.devtools.package value could reach that display, then identify the relevant tests or UI coverage. Done means the originating package is shown consistently, with any added description behavior clarified.
