Update links to section headings after automatic rename

[peeragetalkers]

See:

Automatic/inline update of links to headers and blocks when they are modified (no extra dialog window)

Currently to propagate the change of header text to header links, an explicit user interaction is needed that involves opening a modal window. It would be great if this change is detected automatically/inline and no explicit user action/dialog is necessary. A related FR that is similar to implement: This is something that more realistically can be implemented: https://forum.obsidian.md/t/add-markers-in-the-gutter-for-headings-and-blocks-that-are-referenced-somewhere-else/37708
