Documentation: HID: hid-sensor editing & corrections

Do basic editing & correction to hid-sensor.rst:
- use HID consistently instead of hid
- drop a duplicate word
- change article adjective an -> a
- fix grammar & punctuation
- spell out RW -> read-write
- hyphenate multi-word adjectives

 an ambient light sensor can send illumination data.
 So the implementation has two parts:

 - Individual sensor processing part (sensor drivers)
