fix: Add a trailing wildcard because we don't use an exact path.

We were seeing the following error:

```
  /usr/bin/git add -- requirements scripts/**/requirements
  fatal: pathspec 'scripts/**/requirements' did not match any files
```

Once we introduce wildcards, the whole path needs to be valid so adding
a trailing wildcard to catch all the relevant directories and files.
