[BUG] `cargo build` fails on `1.91.0-beta`

[tanuki-billie]

What is the bug?

Attempting to build the migration tool on the recommended Rust toolchain fails. Multiple packages require a higher version (1.91.1).

How can one reproduce the bug?

cargo build --release with the current file structure.

What is the expected behavior?

The build succeeds.

Do you have any additional context?

Updating rust-toolchain.toml to a higher version solved the issue (I used 1.94.0).
