Unhelpful errors on syntax issues

Start from the script execution path represented by callAsyncFunction and main in the reported dist/index.js stack, and trace how syntax errors from the action code are surfaced. Done means syntax errors identify the relevant line in the supplied script, ideally including the source line, with tests covering the improved output.

Is your feature request related to a problem? Please describe.

Currently problems with action code can cause errors like this:

SyntaxError: Unexpected token '.'
    at new AsyncFunction (<anonymous>)
    at callAsyncFunction (/home/runner/work/_actions/actions/github-script/v7/dist/index.js:[35](https://github.com/dktapps/RestrictedActions/actions/runs/11989435916/job/33425884775#step:4:36)424:16)

I haven't the faintest clue where or why this happened with my code. Plugging it into a linter didn't reveal any problems.

It would be nice if the error output included a line number in the actual action code to show where the problem occurred, or even better printed the line in question.

Here's the code this happened with, if it's relevant:

      - name: "Check if bot's review was dismissed (pull_request_review.dismissed only)"
        id: re-review
        uses: actions/github-script@v7
        env:
          APP_SLUG: ${{ steps.generate-token.outputs.app-slug }}
          REVIEWER_ID: ${{ github.event.client_payload.reviewer_id }}
        with:
          github-token: ${{ steps.generate-token.outputs.token }}
          script: |
            const reviewer_id = process.env.REVIEWER_ID;
            console.log(reviewer_id);
            if (reviewer_id === "0") {
              console.log("No reviewer ID provided, continuing with re-review");
              core.setOutput('skip', 'false');
            } else {
              console.log("Reviewer ID provided: " + reviewer_id);
              const user_info = await github.rest.users.getByUsername({
                process.env.APP_SLUG + '[bot]'
              });
              const bot_user_id = user_info.data.id;
              if (bot_user_id != reviewer_id) {
                console.log(`Not the bot's review that was dismissed (expected user ID: ${bot_user_id}, got: ${reviewer_id})`);
                console.log('Skipping re-review');
                core.setOutput('skip', 'true');
              } else {
                console.log("Bot's review was dismissed, continuing with re-review");
                core.setOutput('skip', 'false');
              }
            }
