This updates the annotation for the NodeClockSkewDetected mixin alert to
match the new threshold set.
Original discussion was in this PR: https://github.com/prometheus/node_exporter/pull/1480
I spent an embarrassingly large amount of time trying to figure out how
the heck that alert would mean 300s of clock skew. Turns out the
annotation was just left the same after the threshold change.
