Armada has previously named template files relative to the
`templates` dir, whereas the Helm CLI names them relative
to the chart root. This causes `include`s of these templates
to fail.
This change fixes this, for armada/Chart/v2 docs only, since it
is a breaking change, as some charts may have already aligned
with the existing Armada behavior. When updating a release
previously deployed with armada/Chart/v1, the fixed template
names alone will not cause the release to be updated, as the
diff logic accounts for this.
