fix(docs): bump version of problematic crates

As noted here, rust-lang/rust#113152, the crate `proc-macro2` requires a version > 1.0.60. This issue has been fixed in `zrpc-macros` 0.7.0-alpha.2 and this commit relaxes the constraint on `proc-macro2` in `zenoh-flow-derive`. Signed-off-by: Julien Loudet <julien.loudet@zettascale.tech>
