use curl instead of cr

[pat-s]

More issues than help. Broke again after the most recent 1.7 release when releasing chart 2.0.4.

A curl command to upload to create a GH release directly should be more resilient.

Compared to cr its really unreadable 🙈 whats the current issue with the latest cr release? Just stick with the working version for now if its a known bug?

[pat-s]

Well, cr is also not really readable (why does it need like five flags to do a simple gh-pages publish?) and in the end it is only doing an API call to the GH releases endpoint anyway.

Personally, I'd drop the gh-pages upload entirely.
I am absolutely unhappy maintaining cr solely for this purpose. In all environments/projects I've used in the last 3 years it broke for almost every point release (and in between). In addition, I don't see why one would need an additional packaging wrapper just for helm charts. The OCI variant shows how easy a chart release can be and is on top using helm itself.

So: either somebody else commits to maintain cr from here onward or we drop it. Overall I'd prefer dropping the upload to gh-pages entirely and just keep the OCI variant (and yes I know this is breaking).

This is not an official image from the alpine maintainers. Dont know how trustworthy the author is.

Should be full qualified container name.

Fiddling around with jq curl and json input is also error prone and Im using cr across multiple repos without such issues. But at the end I dont care much, if you think this process is more stable.

@pat-s I see you reverted cr. If you addressed the open comments here, we could also merge this PR.

[pat-s]

To get the release published successfully. I couldn't ensure that the release will work with this PR as I didn't test it on a test repo explicitly.
I didn't want the release to be postponed, which is why I opened #296.

I'll implement a related process in a new repo with write access soon and it seemed overall safer to me to proceed this way with the latest release.

I'll leave it up to you to continue here/decide what to do.
