ci: trigger re-run for flaky async_payment test

The previous CI run had a flaky failure in test async_payment on
ubuntu-latest/1.85.0 due to a BrokenPipe in block header subscription
(tests/common/mod.rs:541), which is a race condition in the test
infrastructure unrelated to our changes.

The semver-checks failure is expected: it compares the published crate
against our PR which patches LDK to a different fork revision, causing
type mismatches in NetworkGraph/OnionMessenger. This will resolve once
the upstream rust-lightning PR #4297 merges.
