Automatic upgrade has failed

[github-actions[bot]]

Oh no! We have failed to automatically upgrade your project to the latest versions of Lean and its dependencies.

If your project currently builds, this is probably because of changes made in its dependencies:

• mathlib: changes

The error could also be caused by upgrading Lean from leanprover-community/lean:3.47.0 to leanprover-community/lean:3.48.0.

You can see the errors by running:

leanproject up
leanproject build
