This bump of versions:

https://github.com/paritytech/polkadot-sdk/pull/4409/files#diff-13ee4b2252c9e516a0547f2891aa2105c3ca71c6d7a1e682c69be97998dfc87eR11936

reintroduced a dependency to proc-macro-crate 2.0.0 which is suffering
from: https://github.com/bkchr/proc-macro-crate/pull/42 this, so bump
parity-scale-codec to a newer version to eliminate the bad
proc-macro-crate 2.0.0 dependency.
