Get total GitHub contributions per year for a user

totalContributionsEx.txt

Using the GiHub GraphQL API contributionsCollection, you can get this pretty easily.
You need to get it for each type of contribution, but then you can add them up. Then
you could loop through a list of users to get this for each of them.
Documentation: https://docs.github.com/en/graphql/reference/objects#contributionscollection 

Example GraphQL API Query:

query totalContributions{
  user(login: "geekygirldawn") {
    name
    contributionsCollection(from: "2021-01-01T00:00:00" to: "2021-12-31T00:00:00"){
      totalIssueContributions
      totalCommitContributions
      totalPullRequestContributions
      totalPullRequestReviewContributions
    }
  }
}


Example Results (JSON format):
{
  "data": {
    "user": {
      "name": "Dawn Foster",
