CRDs in the Release files

[cloudziu]

Hello guys, thank you for your work on the project!

I would like to propose, adding CustromResourceDefinition manifest to your release workflow, or adding them to the repository as a plain manifest file (without included Helm template code). It would be a small quallity of life upgrade.

A great example of that would be:
