feat(tooling): simplify dryrun command (#90)

## Describe your changes
If an .env file is added with these contents:
```
NANGO_SECRET_KEY_DEV=aaa-aaa-aaa
NANGO_HOSTPORT=https://api.nango.dev
```
You can now just run 
```
npm run dryrun -- datadog users d
```

The pattern above being `dryrun $INTEGRATION $SCRIPT_NAME
$CONNECTION_NAME`

Instead of 
```
bash scripts/run-integration-template.bash KEY=aaa-aaa-aaa HOST=https://api.nango.dev datadog dryrun users d
```

Note that this is backwards compatible

## Issue ticket number and link

## Checklist before requesting a review (skip if just adding/editing
APIs & templates)
- [ ] I added tests, otherwise the reason is:
- [ ] External API requests have `retries`
- [ ] Pagination is used where appropriate
- [ ] The built in `nango.paginate` call is used instead of a `while
(true)` loop
- [ ] Third party requests are NOT parallelized (this can cause issues
with rate limits)
- [ ] If a sync requires metadata the `nango.yaml` has `auto_start:
false`
- [ ] If the sync is a `full` sync then `track_deletes: true` is set
