Add missing pressure units to the atmospheric_pressure device class

[Bre77]

Proposed change

The documented unit list for the atmospheric_pressure device class is missing two units it accepts.

atmospheric_pressure and pressure both take their valid units from set(UnitOfPressure), so the same units are valid for both, but the atmospheric_pressure bullet omits mPa and inH₂O. This brings it into line with the pressure bullet in the same files, which already lists the full set.

Pull request overview

Updates the sensor and number integration documentation so the atmospheric_pressure device class lists the same supported units as the underlying UnitOfPressure set (and as the already-documented pressure device class), fixing an omission in the unit list.

Changes:

• Add the missing supported units (mPa and inH₂O) to the documented atmospheric_pressure device class unit list.
• Align the atmospheric_pressure unit list ordering/content with the existing pressure device class unit list in the same pages.
