Describe the bug

Some field of the Project struct have changed type on deps.dev service and are not updated in this library.
Fields are:

• OpenIssuesCount
• StarsCount
• ForksCount

They all should be integer instead of string.

To Reproduce
Steps to reproduce the behavior:

1. Check response from API call of getProject endpoint:

• https://api.deps.dev/v3/projects/github.com%2Ffacebook%2Freact
• https://api.deps.dev/v3/projects/github.com%2Fedoardottt%2Fdepsdev

Expected behavior
This library should update the type of the field to string so it can properly decode the json sent by deps.dev API.
