Links to internal repo

Dear Team,

On request of Clemens Wältken, I am opening this issue to highlight that the documentation is pointing towards internal repositories at least at 2 places:

On the front page:
https://github.com/microsoft/everyonecancode/tree/main?tab=readme-ov-file

Within Track 2, Sprint 00 Env. Setup:
https://github.com/microsoft/everyonecancode/tree/main/Track_2_ToDo_App/Sprint-00%20-%20Environment%20Setup

Best regards,
Maximilian Wiese
