Replace upload-dif with debug-files upload

[szokeasaurusrex]

At these two locations, we call sentry-cli upload-dif. These calls should be replaced with calls to sentry-cli debug-files upload. sentry-cli upload-dif is a hidden alias to sentry-cli debug-files upload created for backwards compatibility, and it is likely to be deprecated and removed in the future.
