Plugins page: Clicking a keyword should search for that keyword

[phated]

I thought about this but didn't implement it. This would make them more usable.

@phated Want to implement this after the deprecate card issue.
For the clear understanding about this issue, I want to ask few questions.

1. Is it correct to think that clicking button in photo below trigger the search and shows list of result?
   
2. After displaying the list the keyword must be in the search-box?
   
3. Kindly asking if I can get the brief explanation about the api request through the GET method? The API request to npm when we tried to get the deprecated package was bit hard to understand( https://registry.npmjs.com/-/v1/search?from=0&text=keywords:gulpplugin%20is:unstable%20not:unstable%20webpack&quality=0.5&popularity=1.0&maintenance=0.1).
