Update Taskade entry to include taskade/taskade repo

[johnxie]

Update Request: Add Taskade public repo link

Hi maintainers, thanks for listing Taskade.

Taskade now has a public open-source repo:

• Repo: https://github.com/taskade/taskade
• Website: https://taskade.com

Could the Taskade entry be updated to include the repo URL (as the main link or an added (Repo) link)?

Suggested backlink:
https://github.com/taskade/taskade
