fix(@schematics/angular): guard schematics should include all guards (CanMatch)

atscott · dgp1130 · commit c33cc0a7abb2 · 2022-11-02T08:49:41.000-07:00
The `CanMatch` guard was added in v14.1 but not added to the list of possible interfaces to implement. This commit adds `CanMatch` to the list of possible interfaces to implement. It has the same type imports as the CanLoad interface. (cherry picked from commit f837f6d)
