iio: light: veml6030: fix ALS sensor resolution

The driver still uses the sensor resolution provided in the datasheet
until Rev. 1.6, 28-Apr-2022, which was updated with Rev 1.7,
28-Nov-2023. The original ambient light resolution has been updated from
0.0036 lx/ct to 0.0042 lx/ct, which is the value that can be found in
the current device datasheet.

Update the default resolution for IT = 100 ms and GAIN = 1/8 from the
original 4608 mlux/cnt to the current value from the "Resolution and
maximum detection range" table (Application Note 84367, page 5), 5376
mlux/cnt.
