dx(yarn): Run `yarn install --check-files` when verify tree fails (#13279)

A common problem is with node packages not existing in `node_modules`, even though `yarn install`
says everything is up to date.  This adds an additional step to check packages against what exists
in `node_modules` and run `yarn install --check-files` if check fails.
This should install the packages missing from `node_modules`.
