fix(doc): generic description for --version/verify

The flags added by addChartPathOptionsFlags() are used for
`helm install` and `helm upgrade` but also for `helm template`,
`helm show` and `helm pull`. Because of the latter three, we should not
use the word 'install' in the description of the --version and --verify
flags.
