docs(helm): change `trunc 24` in base charts

Closes #1744

Merge branch 'docs/change_trunc_length' of https://github.com/wilkers-steve/helm into docs/change_trunc_length

The upper limit for a chart name is 63 characters now instead of
14 or 24 in older versions of Kubernetes. This replaces `trunc 24`
in the example chart provided to `trunc 63` to reflect the new
length available.

Closes #1637
