fix(RUSTSEC-2024-0370)!: bump clap to latest, removing transitive

dependency on `proc-macro-error`.

In bitcoindevkit#1593 it's mentioned that `proc-macro-error` is unmaintained for the
past few years, with no fix other than using proc-macro-error2 instead.

As on our scenario it's merely a transitive dependency of `clap`,
through `clap_derive` feature, which in latest releases doesn't depend on
`proc-macro-error` we can just bump it to latest.

It's valid to note that by bumping it, both examples that relies on clap
are no longer MSRV (1.63) compliant.
