Bug 1934613 [wpt PR 49467] - Tweak fuzzy parameters of dynamic-content-change-rendering, a=testonly

Automatic update from web-platform-tests
Tweak fuzzy parameters of dynamic-content-change-rendering

The failures show that some builders are getting a max channel
difference of 2 and a total pixels different of 5. This patch adjusts
the parameters to allow a total number of pixels different to be 0-20
instead of exactly 20.
