LilyDev3 problems - a translator's point of view

[周 卫星]

Dear developer,

It's me Lex again, the new comer Chinese translator.
The translation is not started yet, for I've tried to apply LilyDev3 
environment on Windows 11, as instructed.
I managed to make a Docker build from the source code (didn't figure out how to 
use the huge release package which failed to be depressed via tar -xf​, any 
comment?).
And here're several problems I met:

  1.
[HIGH] The LilyDev3 docker build is ​**MISSING SOME PACKAGES** and not 
available for work out-of-box! To me it looks like a critical issue - why all 
the bother with Docker when I need to search and install the missing packages 
manually?
Packages I found missing by running configure:
- libgc-dev
- guile-3.0-dev
- texlive-font-utils
- lmodern
The configure completed without error after these were installed.
  2.
[HIGH] "Check state of translation" failed! The repo was latest updated with 
remote, yet the command make -C Documentation ISOLANG=zh check-translation​ 
gives only error:

```cli
 lilydev:~/lilypond-src
$ make -C Documentation ISOLANG=zh check-translation

```

I've got completely no idea what to do at this moment. Same error happened on 
other languages, too.

Kindly help!

Regards,
Lex
