Error messages when following the contributing guide for reviewers

I was trying to review the tutorials by following the steps on the [contributing guide](https://github.com/epiverse-trace/tutorials/blob/main/CONTRIBUTING.md) , however I'm running into errors when using the following functions:

sandpaper::manage_deps()

``Error: ! in callr subprocess.
Caused by error in `renv_snapshot_validate_report(valid, prompt, force)`:
! aborting snapshot due to pre-flight validation failure
ℹ See `$stdout` and `$stderr` for standard output and error.``

sandpaper::build_lesson()

``Error: ! in callr subprocess.
Caused by error in `renv_snapshot_validate_report(valid, prompt, force)`:
! aborting snapshot due to pre-flight validation failure
ℹ See `$stdout` and `$stderr` for standard output and error.``

I'm not sure if this is related to previous [issues](https://github.com/epiverse-trace/tutorials/issues/30) with sandpaper
