minor nit, Get should be capitalized (reminder to change the code as well)

Done. I had used lower-case letter to be consistent with other histograms in
this file
(https://cs.chromium.org/search/?q=f:network.*change+recordhistogram&sq=packag...).
I still think it is better for new histograms to use upper case letter.
