## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->
We checked `git diff` to see if new screenshots were generated. If no
new screenshots were generated then we print a user-friendly message
informing the dev what happened. However, `git diff` does not account
for untracked changes (i.e. new screenshots).
As a result, this prevented new screenshots from being committed.
## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->
- To fix this we use the `-N` flag which is short for `--intent-to-add`.
This adds an entry with no content which causes the new screenshots to
show up when running `git diff`. We later add the contents of the image.
Example test run of this working:

## What is the current behavior?

When the "Update Reference Screenshot" job is run but no new screenshots
are generated, the following error is logged:
```
nothing added to commit but untracked files present (use "git add" to track)
Error: Process completed with exit code 1.
```
This is happening because there are no files to commit when running `git
commit`. Brandy noted that this was confusing since it doesn't actually
tell you why there are no files to commit.
## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by

- If there are no diffs to commit then the update screenshot script will
log a message saying that no screenshot diffs were generated.
Example:
```
⚠️ Error: No new screenshots generated ⚠️
This means that there were zero visual diffs when running screenshot tests.
Make sure you have pushed any code changes that would result in visual diffs.

`action/setup-node@v3` shipped a "breaking" change that requires node
v18. This breaks our dev build release process.
