platform/x86: thinkpad_acpi: Add missing T14s Gen1 type to s2idle quirk list

[ Upstream commit 9a469c6dfab38326f99f105386db84230be09ee3 ]

From the commit message adding the first s2idle quirks:

> Lenovo laptops that contain NVME SSDs across a variety of generations have
> trouble resuming from suspend to idle when the IOMMU translation layer is
> active for the NVME storage device.
>
> This generally manifests as a large resume delay or page faults. These
> delays and page faults occur as a result of a Lenovo BIOS specific SMI
> that runs during the D3->D0 transition on NVME devices.

Add the DMI ids for another variant of the T14s Gen1, which also needs
the s2idle quirk.
