Fix with-docker example dockerfile (#33695)

krystxf · ijjk · web-flow · commit 33784f134248 · 2022-01-27T17:30:52.000Z
Fixed `dockerfile` in `with-docker`  example

## Bug

- error when executing `docker build -t nextjs-docker .` - `yarn.lock` file is missing

 ## Documentation / Examples

- edited to not fail when `package-lock.json` or `yarn.lock` are not found
- example: use `with-docker` example

- [x] Make sure the linting passes by running yarn lint
