Subject: [PATCH] fix(ngcc): add default config for `ng2-dragula` (#33797)

The `dist/` directory has a duplicate `package.json` pointing to the
same files, which (under certain configurations) can causes ngcc to try
to process the files twice and fail.

This commit adds a default ngcc config for `ng2-dragula` to ignore the
`dist/` entry-point.

Fixes #33718

PR Close #33797
