Fix CI (#332)

* Update pre-commit actions

This was done by running "pre-commit autoupdate --freeze".

* Remove pre-commit only dependencies from requirements.in

Including them in the file would create the illusion that those were the
versions actually used in CI, but they are not. The exact versions are
determined by the pre-commit hooks which are pinned in
.pre-commit-config.yaml.

* Ansible Lint: Fix role-name[path]

* Ansible Lint: Fix name[play]

* Ansible Lint: Fix key-order[task]

* Ansible Lint: Fix jinja[spacing]

* Ansible Lint: Fix no-free-form

* Ansible Lint: Fix var-naming[no-reserved]

* Ansible Lint: Fix yaml[comments]

* Ansible Lint: Fix yaml[line-length]

* Ansible Lint: Fix name[casing]

* Ansible Lint: Fix no-changed-when

* Ansible Lint: Fix fqcn[action]

* Ansible Lint: Fix args[module]
