Update index.yaml

[klubi]

Without this it's impossible to use v0.2.0 version.

apiVersion: v2
name: some
version: 1.0.0
dependencies:
  - name: wiremock
    version: 0.2.0
    repository: https://wiremock.github.io/helm-charts
    condition: wiremock.enabled

when running helm dependency update below log is printed

index.go:370: skipping loading invalid entry for chart "wiremock" "0.2.0" from /Users/klubi/Library/Caches/helm/repository/wiremock-index.yaml: validation: chart.metadata.name is required
Error: can't get a valid version for repositories wiremock. Try changing the version constraint in Chart.yaml

@gitkent I'm trying to use this helm chart, but I cannot use version 0.2.0 from the repo without this fix.
For now, only using the templates locally....
