## Summary
While working on potential bug fixes with temporary files on Windows (I
think I am currently ecountering the same issue as #2810)
I noticed that sub-workspaces were not all having the same `tempfile`
version. And they were not relying on the cargo root project dependency.
I don't know at all if it was done on purpose or not.
(I also wanted to override the root dependency with a local source but
it was not possible due to sub-workspaces not relying on the same).

The root lockfile already pinned to the `3.14.0`. Some sub-workspaces
were depending on the `3.12.0`, some others on the `3.14.0`. So I
updated the root `Cargo.toml` to the `3.14.0`.

Feel free to decline if it was done on purpose! No worries at all
🙂

Thanks!
