stages/containers: don't validate keys

Browse source 
In Python 3.14 configparser started validating keys. We use hacky bits
to write duplicate keys which means we have delimiters in our keys which
is now no longer allowed.

Let's explicitly turn off key validation for now as suggested by
mhroncok in [1].

# In Python 3.14 configparser validates key contents and doesn't allow delimiters in them. Due to the hack several
# lines above we explicitly use some interesting behavior to write duplicate keys by including the delimiter in them.
# We need to disable the key validation check. Thanks to mrhoncok [1] for this workaround. In time we should probably
# revisit how we write unit files because configparser isn't the best for this.
