appveyor.yml - add VS image info to build log, Ruby 2.6 [skip travis]

Ruby trunk failed. The build is done three times a day, and saves three files. Every 50 to 100 builds, a file is missing. Last build, it was the actual build archive. I forced a build, and (of course) the three artifacts exist.

I tried 2.6 on my AppVeyor yesterday too, and it succeeded. A previous test of master also succeeded. OK, I understood what you want to do and I think it's correct. The failures on AppVeyor are just an AppVeyor's strange behavior...

I don't think much about it I just do it, and I'm going to see how it goes for a while.

Tentatively, the merge commit of this Pull Request succeeded.

As mentioned, the trunk failure here in the PR was AppVeyor's strange behavior...

But, I took a look at when there were trunk build issues (both Appveyor & Travis), on 15-Feb. I don't think the Travis build is tested, but trunk will always load a passing build, even if more recent builds are failing. Odd thing, the failure here was when building an extension gem (racc), and the build code was looking for defines.h in include/ruby-2.7.0, but it's always been in include/ruby-2.7.0/ruby. Obviously, it's been fixed...

Anyway, rather than commenting out trunk, in Appveyor:

matrix:
  allow_failures:
    - ruby_version: _trunk

Feel free to ping me if there are windows issues. Thanks for your work here and in reline. It was almost passing all the readline tests last time I checked.

JFYI, on Windows, trunk, 2.5 & 2.6 include readline.so, but also include rb-readline, and have it enabled. I look forward to replacing rb-readline with reline...
