Fix Tailwind CSS package README GitHub links

[pavan-sh]

Summary

These package READMEs referenced the wrong GitHub org (tailwindcss/tailwindcss) and outdated branches (master/next) for common project links.
Update them to point at tailwindlabs/tailwindcss on main for releases, license, discussions, and contributing docs.

Test plan

Docs-only change: No test required.

These changes affect badge links for releases and licenses, as well as external links for community discussions and contributing documentation. No functional code or exported API declarations are modified. Each README file has four lines added and four lines removed.
