v2.10.6

This release is finally fixing the problem of outdated builds of published date-io/* releases.

We apologize 🙏 for this publishing issues causing 2.10.0-2.10.5 releases. If you installed any of these versions please update to the latest, those builds are broken and deprecated on npm.

From now on versions of @date-io/* will always be synchronized with @date-io/core package and will never cause version conflict or be outdated.
