Crystal 0.28.0 Released

This is a big release that includes some new language constructs, tidying up some existing features, many interesting additions to the std-lib and important changes for the much awaited multi-threading and windows features. Read about this change in #7562 and in the new entry on the docs

The compiler includes a bunch of fixes and improvements related to how some code constructs were handled. got some polishing again but given the impact of the changes we wanted to include, and the new deprecation support we are using that to offer a migration path.
