Fix invalid escape sequence in EKS Hook module

[Taragolis]

Body

Right now import airflow/providers/amazon/aws/hooks/eks.py raise DeprecationWarning / SyntaxWarning (depends on python version)

{
  "category":"DeprecationWarning",
  "message":"invalid escape sequence \\s",
  "filename":"airflow/providers/amazon/aws/hooks/eks.py",
  "lineno":79,
  "when":"collect",
  "node_id":null
}

We should avoid to use something that deprecated in Python itself years ago in Python 3.6.

\ in the end of the line make sense only in regular strings, not in triple quoted, however right now it work as intended - remove new line in the end of the line

[!NOTE] This rule right now ignored in statical code checks (provided by ruff rule W605) on module level https://github.com/apache/airflow/blob/79b5443d40545d16f219f4f7dc260257fdf45bbd/pyproject.toml#L392-L393 So it also required to remove this lines from pyproject.toml,

[!WARNING] Ruff Autofix suggest use raw string here, however it is not a case here and better rewrite built this command. Previous attempt https://github.com/apache/airflow/pull/38734 is reverted https://github.com/apache/airflow/pull/38864

Is there more work left in this that I can help with? @Taragolis

There is only one things remaining, that it exact the thing which describe into the issue

This warning which might annoying end users because since Python 3.12+ such warnings become SyntaxWarning, see: https://github.com/python/cpython/issues/98401, which are not ignored by default as DeprecatedWarnings

So if you would like to fix, feel free to make a PR
