Merge bitcoin#30885: scripted-diff: Modernize nLocalServices naming

33381ea scripted-diff: Modernize nLocalServices to m_local_services (Fabian Jahr)

Pull request description:

  The type of the `nLocalServices` variable was changed to `std::atomic<ServiceFlags>` in bitcoin#30807 and I suggested the variable name to get updated with a scripted diff along with it. It wasn't included in the PR but I am still suggesting to do it as a follow-up since I had already prepared the commit.
