build: bump to latest MDC Canary to fix regression

We recently updated to the latest MDC Canary to fix some build issues and be able to use the feature targeting for the form field, but it also came in with a regression. These changes update to a newer Canary version that has a fix for the regression (material-components/material-components-web#5512).
