ansible/pacman_install: update full name for pacman module
This module is now part of the community.general collection (version 6.0.1). Updating accordingly.
The warning message is:
[DEPRECATION WARNING]: community.general.packaging.os.pacman has been
deprecated. You are using an internal name to access the
community.general.pacman modules. This has never been supported or documented,
and will stop working in community.general 9.0.0. This feature will be removed
from community.general in version 9.0.0. Deprecation warnings can be disabled
by setting deprecation_warnings=False in ansible.cfg.
