Bug [3.0.0-rc2] bad character U+002D '-'

[SteelAlloy]

When installing the chart generated by Katenary, Helm throws the following error :

❯ katenary convert -c compose.yaml -o ./chart
❯ helm upgrade --install gitlab ./chart
Release "gitlab" does not exist. Installing it now.
Error: parse error at (gitlab/templates/gitlab-postgres/gitlab_postgres.volumeclaim.yaml:1): bad character U+002D '-'
