tpl/transform: Unmarshal whitespace removal produces invalid YAML

[jmooring]

This change in v0.136.3 removes whitespace from a YAML string before we unmarshal it:

42f37b4#diff-ac3fd377a127dfceca723e62fdde1176ab715eaa2068402c3e2777a47e409414R115

I just ran into this in the wild...

{{ $yaml := `
  a:
    b: 1
    c: 2
  d:
    e: 3
    f: 4
`}}

{{ transform.Unmarshal $yaml }}

When we remove the leading whitespace, the outermost key is no longer indented, but later keys that should be at the same level are still indented 2 spaces, producing invalid HTML.

error calling Unmarshal: "_stream.yaml:3:1": failed to unmarshal YAML: yaml: line 3: did not find expected key
