Fix eks.py SyntaxWarning: invalid esape sequence '\s'

[dabla]

When running breeze I always get the following warning:

breeze ci-image build --use-uv --uv-request-timeout 900

eks.py:79: SyntaxWarning: invalid escape sequence '\s'

This pull request fixes this by making the COMMAND string in eks.py a raw string.

Hi @dabla, it seems this PR introduced a bug. All our system tests related to AWS EKS started to fail for the same reason. See error below:

ERROR [root] exec: failed to decode process output: Expecting value: line 1 column 41 (char 40)

I am afraid the bug impacts not only AWS system tests but also users. I will create a PR to revert this PR.
