Subject: [PATCH] build(docs-infra): examples should not run ngcc for all
 formats (#28984)

Currently when adding the example boilerplate to all
examples with Ivy enabled, we run Ngcc and transform
all found formats. This potentially slows down the build and
is not necessary as we only need the "fesm5" and "fesm2015" bundles.
