Please publish the version compatible with Dart SDK 3.12

TL;DR: that's #4218 for 3.12.

The version bump should happen on January, 6th, so there's time, but I'm preparing the version bump cl in advance.

@Markzipan the point of the upper bound is to guard against breaking changes to SDK internals that the web compiler builders depend on ... do you know if 3.11 is far enough along that we can up the bound, or should this wait? Thanks!

[Markzipan]

This should be safe! We haven't introduced anything breaking that needs to be addressed in the web compilers (from my knowledge).
