Update package.json metadata to link to package directory inside monorepo

Problem

The repository and homepage links on npmjs website link to the GitHub repo, and not the directory inside monorepo.

For example, view @changesets/cli:

• Repository: https://github.com/changesets/changesets/tree/main
• Homepage: https://github.com/changesets/changesets/tree/main#readme

Proposed solution

Change package.json metadata such that home page links to source code on GitHub and repository links to root folder of monorepo

For example, the medata for @changesets/cli should be:

• Repository: https://github.com/changesets/changesets
• Homepage: https://github.com/changesets/changesets/tree/main/packages/cli

For @changesets/cli, this can be done by updating the following in package.json

{
  "homepage": "https://github.com/changesets/changesets/tree/main/packages/cli",
  "repository": {
    "type": "git",
    "url": "https://github.com/changesets/changesets.git",
    "directory": "packages/cli"
  }
}

This is similar to how it's done for @aws-sdk/client-s3
