[Enhancement]: Use correct npm package name on documentation

[kralonur]

What would you like us to improve?

On api reference pages for ccip, wrong or old package names are being used.

For example, instead of:
If you use NPM: npm install @chainlink-ccip/contracts --save

If you use Yarn: yarn add @chainlink-ccip/contracts

This should be used:
If you use NPM: npm install @chainlink/contracts-ccip --save

If you use Yarn: yarn add @chainlink/contracts-ccip

How important it is?

It is important for developers who follow documentation insead of checking package name from npmjs
