Where and how did you try this?

This error is from the host, not the engine VM.
I thought I might know the reason, but checking further shows me I
still do not...
Adding a few other people that might be able to help.
What I did check so far (only by looking at code and testing on quite
current CentOS Stream 8, not Rocky Linux):
1. This seems to be a minimal reproducer of your issue, on Stream:
# ansible -m firewalld -a state=enabled localhost
2. This seems to be a minimal "fix", for the above:
# ansible -m firewalld -a state=enabled -c local -i localhost, all
Meaning: Specifying an inventory, instead of directly a host. See also e.g.:
https://docs.ansible.com/ansible/latest/reference_appendices/interpreter_discovery.html
https://stackoverflow.com/questions/61561744/why-do-i-get-different-python-version-for-implicit-and-explicit-localhost
Running both of them with ANSIBLE_DEBUG=1 and -vvvvv shows that there
are differences in which python is used, but I failed to completely
understand how it's done.
A wild guess as to why this fails on Rocky Linux:
https://github.com/ansible/ansible/blob/devel/lib/ansible/config/base.yml#L1528
Perhaps there should have been code that would have caused the code
using the this map, to use 'redhat', but perhaps this does not work
well there.
If the "fixed" version (2.) above fails on Rocky Linux, perhaps open a
ticket on Rocky Linux's ansible packaging and have it fixed, then try
hosted-engine deployment again.
Hope this helps at least a bit...
Best regards,
