Mongodb stuck at version 5

I have been running a mongodb version 4 for a while on my amazon ec2 with amazon linux 2013. I have then successfully updated MongoDB to version 5 by following the documentation:
https://www.mongodb.com/docs/v5.0/tutorial/install-mongodb-on-amazon/
By adding the repo file, sudo yum update will automatically update MongoDB.

I then did the same with MongoDB 6:
https://www.mongodb.com/docs/v6.0/tutorial/install-mongodb-on-amazon/

I added a repo file etc/yum.repos.d/mongodb-org-6.0.repo with the content

[mongodb-org-6.0]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/amazon/2013.03/mongodb-org/6.0/x86_64/
gpgcheck=1
enabled=1
gpgkey=https://www.mongodb.org/static/pgp/server-6.0.asc

I then run

sudo yum install -y mongodb-org

But I get

amzn-main                                                                                                       | 2.1 kB  00:00:00

What could be the reason it doesn't find any version 6 of MongoDB and thinks version 5 is the latest?

I also see the same issue if I try to force install version 6:

sudo yum install -y mongodb-org-6.0.4 mongodb-org-database-6.0.4 mongodb-org-server-6.0.4 mongodb-org-mongos-6.0.4 mongodb-org-tools-6.0.4

They don't host v6 there at the time of answering. If you open the url now it's only mongosh and db tools there.

Must be a rare case when documentation is not up-to-date, but ahead-the-date =)

If you feel adventurous, you can try a release candidate v6.0.0.rc1 from testing repo:
