feat: add new hooks for healthcheck

[GreyXor]

Context: #73 (comment)

This add AddBeforeHealthCheckHook and AddAfterHealthCheckHook

Todo:

• tests
• doc

I can use it like so

do.DefaultRootScope.AddBeforeHealthCheckHook(func(scope *do.Scope, serviceName string) {
    slog.Debug(serviceName + " service health check")
})

do.DefaultRootScope.AddAfterHealthCheckHook(func(scope *do.Scope, serviceName string) {
    slog.Debug(serviceName + " service health checked")
})
