Execute limited request for diff commits instead of preloading

See merge request gitlab-org/gitlab!19485

The number of diff commits can be overwhelming sometimes and
preloading them and iterating over them using map
can be very expensive

We'd better make multiple limited requests (even if it's N+1)
then running into a subtle case when thousands of elements
are loaded into memory and iterated

Only show previewable files in Vue file listing
