set-output command is deprecated warning when running education/autograding action

[DerekHarter]

Currently I receive the following warning when running the education/autograding@v1 action in my github classroom:

Warning: The `set-output` command is deprecated and will be disabled soon. Please upgrade to using Environment Files. For more information see: https://github.blog/changelog/2022-10-11-github-actions-deprecating-save-state-and-set-output-commands/

From the link provided, these workflows may stop working on 1st June 2023 instead of just giving warnings. From the description of Patching your actions and workflows, they indicate that the @actions/core package should be updated to v1.10.0. I am just guessing, as I was looking around to try and fix it myself, but this may be as simple as updating the 'autograding/package.json' file to list the dependency as something like:

  "dependencies": {
    "@actions/core": "^1.10.0",
