ci: deal volume server tests across shards instead of bucketing by letter (#10576)

Browse Source 
Both workflows split the suite with ^Test[A-H] / ^Test[I-S] / ^Test[T-Z].
Test names cluster, so shard 2 drew 50 of the 114 grpc tests and 30 of
the 64 http ones, and spent 13m51s against 7m48s and 9m09s for its peers.

Listing the tests and dealing them out one at a time splits them 38/38/38
and 21/22/21, and keeps splitting evenly as tests are added. The pattern
is computed once into the environment rather than repeated in the summary
step, where the two copies had to be kept in agreement by hand.
