I have already done a preliminary review for you, and I hope to help you do a better job.
Based on the pull request title and description, it seems that the main goal of this change is to build Grafana without pulling a specific file that usually results in a 403 error.

Looking at the diff, we can see that the change involves modifying the build steps to export a couple of environment variables and run a new target called "grafana_without_pull". It appears that this new target is meant to handle the build process without pulling the problematic file.

One potential problem with this change is that we don't know what the problematic file is or why it causes a 403 error. Without this context, it's hard to determine if this change is a proper solution or if it's just masking a more significant problem. It would be helpful to have more information about the root cause of the issue and why this new target is the best solution.

Another issue is that the new target name is not very descriptive. It's not clear what this target does or how it differs from the previous one. Providing more information in the target name or adding a comment could make it easier for future readers to understand the code.

Lastly, it would be a good idea to add some tests to ensure that the new build process works correctly and that the problematic file is no longer causing issues.

Overall, this change seems reasonable, but it would be helpful to have more context and tests. Here are some suggestions for improvements:

• Add a comment explaining why the problematic file causes a 403 error and why this new target is the best solution.
• Rename the new target to something more descriptive, like "build_grafana_without_problematic_file".
• Add tests to ensure that the new target works correctly and that the problematic file is no longer causing issues.
