Publish new release for DMD's CI

[JinShil]

msgpack-d is one of two projects causing a Jenkins CI failure for DMD (dlang/dmd#8241) and preventing us from moving forward with a deprecation. Looking through the code in msgpack-d's master branch, it appears the fix has already been made, but it needs to be tagged and released for DMD's CI to pick it up.

Ping @repeatedly? The last non-beta release can't compile due to errors:

../../.dub/packages/msgpack-d-0.9.6/msgpack-d/src/msgpack.d(3670,15): Error: catch statement without an exception specification is deprecated
../../.dub/packages/msgpack-d-0.9.6/msgpack-d/src/msgpack.d(3670,15):        use catch(Throwable) for old behavior
dmd failed with exit code 1.

@AndrejMitrovic You want non beta version, right?

[AndrejMitrovic]

Yeah, it would be great to have. I'm not sure if I can use the beta version in dub, for example.
