e.g. if user has `rstudio-2.2.5` (chart version)
installed in his namespace, this would return
"RStudio: 1.2.1335+conda, R: 3.5.1, Python: 3.7.1, patch: 10"

Also bear in mind that Helm added this `appVersion`
field only "recently" so if a user has an old
version of a tool chart installed this would return
`None` as we can't determine the tool version
as this information is simply not available
in the helm repository index.
