Script link from wiki died because file was moved

I'm not sure if this is the correct place to report this,

But this [recent commit](https://github.com/audacity/audacity/commit/1bf83f2e20f48fb9fa56529494dceddf9eee4db0), moving files around, broke a couple links on the [wiki page](https://manual.audacityteam.org/man/scripting.html) for scripting:

The links have moved to [this directory instead](https://github.com/audacity/audacity/blob/master/au3/scripts/piped-work)

Open the scripting wiki page and inspect the broken script links shown in the issue, then compare them with the au3/scripts/piped-work directory in the linked commit. Update the links to their current locations and verify that each one opens correctly.
