Replaced test.ping with test.version 
Result of issue #52277

Any where `test.ping` still exists in the docs was left
because of the context in those docs.

Targeting using Grains

Grain data can be used when targeting minions.

For example, the following matches all CentOS minions:

salt -G 'os:CentOS' test.version

Match all minions with 64-bit CPUs, and return number of CPU cores for each matching minion:

salt -G 'cpuarch:x86_64' grains.item num_cpus

Additionally, globs can be used in grain matches, and grains that are nested in a dictionary can be matched by adding a colon for each level that is traversed. For example, the following will match hosts that have a grain called ec2_tags, which itself is a dictionary with a key named environment, which has a value that contains the word production:

salt -G 'ec2_tags:environment:*production*'
