ci: fix clippy check to exclude example crates

The example crates contain code that isn't accepted by the
1.63.0 version of the compiler (e.g. `is_multiple_of`).

Since the MSRV of the wallet library is currently 1.63.0, and
clippy is configured to adhere to that, we exclude the example
crates from the clippy check enforced by CI.
