Original Reddit post links to an old revision of the repo

[DrymarchonShaun]

The link for this repo in the original reddit post is to an older revision - bfdd8d4e9dce94def22d21b0e4ac8b5e49ebadeb.

Unless this is intentional, it should probably be replaced with https://github.com/eukatree/Bambu_CustomGCode/blob/main/P1P/change_filament_noAMS_P1P_0.4nozzle.gcode (I think that's the right file?) so that it always links to the most recent version.
