can't publish charts with semver build postfix (aka, cr breaks if + in chart version)

[itewk]

Issue

helm states that the version in Chart.yaml supports SemVer, which includes an option for a build section (+BUILD) (https://semver.org/#backusnaur-form-grammar-for-valid-semver-versions).

But, when i try to use the chart releaser with a helm chart with a version of 0.1.0-edge1+SHA-abc123 it fails, if I drop the + to 0.1.0-edge1 it works. based on the error message it looks like some issues with escaping the +.

Same here, actually the hot potatoe is in the mix between GH which provides a link url escaped (https://github.com/jlpedrosa/helm-chart/releases/download/2.11.2%2BChart1/unpoller-2.11.2+Chart1.tgz) and the chart releaser, not the action.

helm/chart-releaser#406 this fixes it.
