Add star counts to popular open-source tools

[hammadhaqqani]

Adding GitHub star counts next to popular open-source tools would help users quickly gauge adoption and community size.

Example format:

- [K8sGPT](https://github.com/k8sgpt-ai/k8sgpt) - AI-powered Kubernetes troubleshooting... ⭐ 5.2k

Note: We need to be careful this doesn't break awesome-lint (descriptions must end with a period). We may need to put star counts before the description dash.

This is a great first contribution - pick a category and add star counts!
