docs: update ivy compatibility guide with latest changes (#33675)

This commit removes one of the expected Ivy changes because we have
decided to change the behavior to be more backwards-compatible.

It also adds a bug fix that is technically breaking to the list of
expected changes.

 - Special injection tokens (e.g. `TemplateRef` or `ViewContainerRef`) return a new instance whenever they are requested (previously, instances of special tokens were shared if requested on the same node). This primarily affects tests that do identity comparison of these objects.
 
 - ICU parsing happens at runtime, so only text, HTML tags and text bindings are allowed inside ICU cases (previously, directives were also permitted inside ICUs).
