eldritch horrors 279e30e7ef build: replace changelog-d with local script
hacking changelog-d to support not just github but also forgejo and
gerrit is a lot more complicated than it's worth, even moreso since
the entire thing can just as well be done with ~60 lines of python.
this new script is also much cheaper to instantiate (being python),
so having it enabled in all shells is far less of a hassle.

we've also adjusted existing release notes that referenced a gerrit
cl to auto-link to the cl in question, making the diff a bit bigger

closes lix-project/lix#176

synopsis: Duplicate attribute reports are more accurate
cls: 557
---
Duplicate attribute errors are now more accurate, showing the path at which an error was detected rather than the full, possibly longer, path that caused the error.
Error reports are now
```ShellSession
$ nix eval --expr '{ a.b = 1; a.b.c.d = 1; }'
error: attribute 'a.b' already defined at «string»:1:3
at «string»:1:12:
1| { a.b = 1; a.b.c.d = 1;
| ^
```
instead of
```ShellSession
$ nix eval --expr '{ a.b = 1; a.b.c.d = 1; }'
error: attribute 'a.b.c.d' already defined at «string»:1:3
at «string»:1:12:
1| { a.b = 1; a.b.c.d = 1;
| ^
```
