Add Socket Security badges

[steinybot]

📋 Description

Please add badges for Socket Security.

For example

Socket have their own badge but it doesn't have all the options that an official badge has.

Given that Socket is now integrated directly into npmjs via the "Analyse security with Socket" button (https://www.npmjs.com/package/gsd-pi) I think this deserves official support. It might also be desireable to have badges for the other aspects of the security rating such as licenses.

Hi @steinybot 👋

I'd love to take a stab at this! Before I start, a few questions for the maintainers:

1. Is there a public Socket API endpoint we can use without authentication?
2. Would the approach be similar to existing security badges (e.g. Snyk)?
3. Should this be scoped to just the overall security score first, or include license/vulnerability breakdowns too?

Happy to start with a simple security score badge and expand from there!

Hey guys. I found something on the README of the socket-registry package. Try adding the badge to your README in this format:
[![Socket Badge](https://socket.dev/api/badge/npm/package/@[ YOUR ORGANISATION ]/[ YOUR PACKAGE NAME ])](https://socket.dev/npm/package/@socketsecurity/registry)

Here is an example
[![Socket Badge](https://socket.dev/api/badge/npm/package/@socketsecurity/registry)](https://socket.dev/npm/package/@socketsecurity/registry)

Hi! I'd like to work on this. Quick question before I start —
does Socket have a public unauthenticated endpoint for package
scores, or does every request require an API token?

If auth is required, would this be implemented as a
user-configured auth badge
similar to how some other private service badges work?

Happy to proceed once I know the intended approach!
