chore: Make Muffet ignore 403 HTTP Status Codes

Description

Make Muffet (the link checker) ignore 403 HTTP Status Codes, as tools like Cloudflare usually trigger them.

Removed link to nonexistent GitHub project.

@mrjones-plip @esthermmoturi I noticed that the main reason for which the link checker fails is 403 statuses (most probably triggered by tools like Cloudflare). I suggest we add 403 to the list of accepted codes. This will avoid adding more exclude links to muffet.sh.

Additionally, as most of the excluded links are due to 403s, I suggest we remove them from the muffet.sh file.

Sure - let's give it a try!

@mrjones-plip @esthermmoturi:

• I removed the links that were returning 403s from the exclude list in muffet.sh
• I upgraded muffet to the latest version so we can use the accepted-status-codes functionality.

Any concerns with this approach?

@andrablaj - no concerns - still looks good!

Let's check the results of the run on ~Monday to ensure it's working as expected (false negatives being the main concern).
