attributes: bump minimum version of proc-macro2 to 1.0.60 (#2732)
Browse files Browse the repository at this point in the history
As part of landing #2728, I noticed that the `-Zminimal-versions` check fails
due to proc-macro2 1.0.40 referencing a since-removed, nightly-only
feature (`proc_macro_span_shrink`). Since this change doesn't change the MSRV
of `proc-macro2` (or `tracing`, for that matter), this feels like a safe change
to make.
