[DOCS] readme.md points to a roadmap that seems out of date

Is there an existing issue for this?

• I have searched the existing issues

This is a CLI Docs Problem, not another kind of Docs Problem.

• This is a CLI Docs Problem.

Description of Problem

Under the 'Links & Resources' section, there is a link to a public roadmap. Clicking it takes you to Github public road maps with npm selected. It looks like the last entry is from 2023, and doesnt represent the current npm roadmap.

[Roadmap](https://github.com/orgs/github/projects/4247/views/1?filterQuery=npm) - Track & follow along with our public roadmap

Potential Solution

Update to point at the current roadmap, update the link to include appropriate filters to show the current roadmap if it is in fact still being used, or point at the new location of the roadmap.

Affected URL
