feat(ansible): add fs.file-max and fs.aio-max-nr to tuned profile (#2228)

* feat(ansible): add fs.file-max and fs.aio-max-nr to tuned profile

This update includes the addition of two key sysctl options to the
PostgreSQL tuned profile:
- fs.file-max: increased to 312139770
- fs.aio-max-nr: increased to 1048576

These changes are aimed at improving system-level performance and resource
availability for PostgreSQL. Minor formatting and linting adjustments are
also included to align with project standards.

* ci: trigger CI workflow with empty commit
