fix: support cookie v2.x (#361)

* fix: support cookie v2.x

 v2 removed the / exports in favour of
/, which broke every route that
sets or reads a cookie (all requests returned 500).

- adapt to the new cookie@2 API while keeping the historic
   /  signatures
  for @fastify/cookie's own public API (fastify.parseCookie,
  fastify.serializeCookie, module.exports.parse/serialize)
- bump the  dependency to ^2.0.0
- fix README links that pointed to now-outdated  v1 anchors

* refactor: update index.js

 ### Rotating signing secret
 
 Key rotation is when an encryption key is retired and replaced by generating a new cryptographic key. To implement rotation, supply an `Array` of keys to `secret` option.
 
 **Example:**
+
 ```js
 fastify.register(require('@fastify/cookie'), {
   secret: [key1, key2]
@@ -272,11 +275,13 @@ fastify.register(require('@fastify/cookie'), {
 The plugin will **always** use the first key (`key1`) to sign cookies. When parsing incoming cookies, it will iterate over the supplied array to see if any of the available keys are able to decode the given signed cookie. This ensures that any old signed cookies are still valid.
 
 Note:
+
 - Key rotation is **only** achieved by redeploying the server again with the new `secret` array.
 - Iterating through all secrets is an expensive process, so the rotation list should contain as few keys as possible. Ideally, only the current key and the most recently retired key.
 - Although previously signed cookies are valid even after rotation, cookies should be updated with the new key as soon as possible. See the following example for how to accomplish this.
 
 **Example:**
+
 ```js
 fastify.get('/', (req, reply) => {
   const result = reply.unsignCookie(req.cookies.myCookie)

 ### Custom cookie signer
 
 The `secret` option optionally accepts an object with `sign` and `unsign` functions. This allows for implementing a custom cookie signing mechanism. See the following example:
