Update urllib3 library version

[GGP1]

Description

Adds the urllib3==1.26.18 library to be compatible with the docker version used.

Used 4.7.2 as the base branch because it's the version used in production and this needs to be fixed as soon as possible.

Since the dependencies in our requirements.txt file force the version to be docker==4.2.0 and urllib3==1.26.5, if we change the documentation to be docker==6.1.1 we would need to modify these in the embedded interpreter to keep consistency.

An alternative to this could be adding the urllib3==1.26.5 version in the docs commands to limit the searched urllib since it is required to be >=1.21.1, and open an issue to upgrade docker for a minor version. Also, consider that an update on the urllib3 dependency is currently ongoing.

LGTM!

As @fdalmaup mentioned, urllib3 is being upgraded to 1.26.18 to fix some vulnerabilities.

Since said change is just a patch, there should be no compatibility issues, but can you ensure that this is the case and, if so, use said version in the docu as well? This way we prevent users from installing a version with known vulnerabilities (1.26.5).

It would also be nice to open a new issue to upgrade the docker version in the future, both in the embedded python and in the documentation for agents.
