### Summary

This is a follow up to issue #74481, which was closed, but the fix doesn't address the problem described in this issues.
Here a  (slightly modified) copy of my comment on the above issue:

PR #74721 doesn't solve the problem reported in issue #74481.
This PR adds a new `ansible_distribution_minor_version` fact.
But issue #74481 is about the `ansible_distribution_version` fact sometimes doesn't include the minor version.

Here a list of `ansible_distribution_version` facts gathered for my Debian hosts:
6.0.8
7.6
7.7
7.11
8
8.2
8.10
8.11
9.6
9.12
9.13
10
11

You see that for Debian 8 `ansible_distribution_version` is sometimes with and without the minor version.
From Debian 10 the fact doesn't include the minor version.

For CentOS `ansible_distribution_version` always include the minor version:
7.4
7.5
7.6
7.8
7.9
8.3
8.4
8.5

To make `ansible_distribution_version` consistent between distributions the minor version should be added to this fact for Debian hosts.
