proposal to add troubleshooting guide for WSL2 / Ubuntu setup

**Description**
While sitting up Fablo on Ubuntu (WSL2), I encountered a few environment-specific challenges that aren't fully covered in the current README.md. These include docker-compose versioning issues and specific flag requirements (like -d vs --detach).
**Proof of Work**
I have successfully deployed the local Hyperledger Fabric network after resolving these issues.

**Proposed Contribution **
I would like to contribute by adding a Troubleshooting section to the documentation. This will help new contributors (especially those on Windows /WSL2) to get started faster without getting stuck on environment errors.
I have already forked the repo and I'm ready to submit a PR with these updates.
Please let me know if I should proceed!
