updated NimYAML to 0.16.0

[flyx]

This updates NimYAML to current 0.16.0 release.

• uses alpine:edge which provides a decently up-to-date nim package, dropping the requirement of manually installing nim. Sadly the package is not contained in any stable release yet. Testing showed that this does not lead to errors during consolidation into the apline-runtime-static image.
• simplifies the testing code; +STR/-STR are now provided by NimYAML

Hey @flyx !

I have to try this out especially with the two Haskell libaries which had problems with the newer alpine images.
See #8

So I might not be able to update this until we resolve the Haskell issues

Hi @perlpunk :)

As I understand it, alpine edge is only used for the isolated NimYAML build image, so other images wouldn't be affected. Alpine seems to make a new release from edge in November so it might be worth to wait for that.

Maybe using a newer release can help fix the Haskell problem as well? Did you try using the 3.14.0 branch yet? It seems to have a newer ghc version available…

It's true that the image is isolated, but we still build the yaml-editor from it, and this currently only works with an image having all libraries.
At some point I would like it to work with separate independent images, but for now...

I'll try out the haskell stuff on the newest alpine and see if it works...

I tested alpine 3.15 but the haskell stuff still doesn't work, so I just updated NimYAML, thanks =)
Looks good on the test matrix: https://matrix.yaml.info/

Finally I have a solution where I can just use independent images for each runtime, look for "daemon" in the readme.
Anyway, now I can update the nim builder.
Maybe you want to rebase your PR?

[flyx]

Okay, since NimYAML is already updated I just simplified the dockerfile to use the Nim package from alpine:3.15.

Thanks, merged!
