Ensure retrieval of hugepage size in check mode

[vitabaks]

This update adds check_mode: false to the tasks retrieving Hugepagesize and HugePages_Total values from /proc/meminfo. This ensures these tasks are executed even in Ansible’s check mode, allowing necessary data to be consistently retrieved for subsequent calculations.

Before:

TASK [pre-checks : HugePages | info] *******************************************
ok: [172.30.58.35] => {
    "msg": {
        "huge_page_size_kb": "0",
        "huge_pages_required": "16896",
        "huge_pages_sufficient": false,
        "huge_pages_total": "0",
        "shared_buffers_gb": "32"
    }
}

After:

TASK [pre-checks : HugePages | info] *******************************************
ok: [172.30.58.35] => {
    "msg": {
        "huge_page_size_kb": "2048",
        "huge_pages_required": "16896",
        "huge_pages_sufficient": false,
        "huge_pages_total": "19020",
        "shared_buffers_gb": "32"
    }
