Helm ignore file temp example

[Magnus010]

In the .helmignore file example (https://helm.sh/docs/chart_template_guide/helm_ignore_file/), there are a couple of lines in the example file that caused issues in our nested Helm charts:

`# Match any file under subdir matching temp*
/temp

//temp*`

These lines caused our nested Helm charts to not render correctly as the //temp* matched the subchart templates folder. Took quite a bit of head scratching to figure this out.

Thank you!
