Fix problem with GitHub Action for welcome message

[namurphy]

In some recent runs of the welcome message GitHub Action, we've been getting an error that we'll need to fix. The error was...

/usr/bin/docker run --name e3916062a188734afea86784690f606b82_d2d698 --label 5364e3 --workdir /github/workspace --rm -e "INPUT_REPO-TOKEN" -e "INPUT_PR-MESSAGE" -e "INPUT_ISSUE-MESSAGE" -e "HOME" -e "GITHUB_JOB" -e "GITHUB_REF" -e "GITHUB_SHA" -e "GITHUB_REPOSITORY" -e "GITHUB_REPOSITORY_OWNER" -e "GITHUB_RUN_ID" -e "GITHUB_RUN_NUMBER" -e "GITHUB_RETENTION_DAYS" -e "GITHUB_RUN_ATTEMPT" -e "GITHUB_ACTOR" -e "GITHUB_TRIGGERING_ACTOR" -e "GITHUB_WORKFLOW" -e "GITHUB_HEAD_REF" -e "GITHUB_BASE_REF" -e "GITHUB_EVENT_NAME" -e "GITHUB_SERVER_URL" -e "GITHUB_API_URL" -e "GITHUB_GRAPHQL_URL" -e "GITHUB_REF_NAME" -e "GITHUB_REF_PROTECTED" -e "GITHUB_REF_TYPE" -e "GITHUB_WORKSPACE" -e "GITHUB_ACTION" -e "GITHUB_EVENT_PATH" -e "GITHUB_ACTION_REPOSITORY" -e "GITHUB_ACTION_REF" -e "GITHUB_PATH" -e "GITHUB_ENV" -e "GITHUB_STEP_SUMMARY" -e "GITHUB_STATE" -e "GITHUB_OUTPUT" -e "RUNNER_OS" -e "RUNNER_ARCH" -e "RUNNER_NAME" -e "RUNNER_TOOL_CACHE" -e "RUNNER_TEMP" -e "RUNNER_WORKSPACE" -e "ACTIONS_RUNTIME_URL" -e "ACTIONS_RUNTIME_TOKEN" -e "ACTIONS_CACHE_URL" -e GITHUB_ACTIONS=true -e CI=true -v "/var/run/docker.sock":"/var/run/docker.sock" -v "/home/runner/work/_temp/_github_home":"/github/home" -v "/home/runner/work/_temp/_github_workflow":"/github/workflow" -v "/home/runner/work/_temp/_runner_file_commands":"/github/file_commands" -v "/home/runner/work/PlasmaPy/PlasmaPy":"/github/workspace" 5364e3:916062a188734afea86784690f606b82

      ^

Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: /node_modules/@octokit/graphql/index.js
require() of ES modules is not supported.
require() of /node_modules/@octokit/graphql/index.js from /node_modules/@actions/github/lib/github.js is an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which defines all .js files in that package scope as ES modules.
Instead rename index.js to end in .cjs, change the requiring code to use import(), or remove "type": "module" from /node_modules/@octokit/graphql/package.json.

Looks like this is a known issue that they're working on a fix for. When it gets fixed, we'll need to update the version of the GitHub Action...hopefully within the next few days.
