403 when pulling additional files from github via "rawusercontent" URL

• Read the Docs project URL: https://app.readthedocs.org/projects/mobgap/
• Build URL (if applicable): https://app.readthedocs.org/projects/mobgap/builds/26276495/

My build downloads some additional files from a secondary github repo using raw.githubusercontent.com URLs. For example in the build above the file https://raw.githubusercontent.com/mobilise-d/mobgap_validation/main/results_file_registry.txt.
This is done using the Python requests library (acutally I am using pooch which uses requests under the hood).

This worked fine when I first tested it, but at some point I was getting 403s (Last build that succeeded: https://app.readthedocs.org/projects/mobgap/builds/26255329/). I assumed that I might have hit some type of rate limit, but even after waiting for 24h+ the error remains.

Running the build locally and in the Github CI works, so it seems to be specific to the RTD infrastructure.
