Dockerfile missing locale

[TristanRobitaille]

The Docker image, at least when running it on Apptainer, doesn't have locale settings. This leads make docs to fail.

Singularity> make docs
make -C docs html
make[1]: Entering directory '/scratch/sem24h24/Deeploy/docs'
Traceback (most recent call last):
  File "/usr/local/bin/sphinx-build", line 8, in <module>
    sys.exit(main())
  File "/usr/local/lib/python3.10/dist-packages/sphinx/cmd/build.py", line 546, in main
    locale.setlocale(locale.LC_ALL, '')
  File "/usr/lib/python3.10/locale.py", line 620, in setlocale
    return _setlocale(category, locale)
locale.Error: unsupported locale setting
make[1]: *** [Makefile:21: html] Error 1
make[1]: Leaving directory '/scratch/sem24h24/Deeploy/docs'
make: *** [Makefile:354: docs] Error 2

Running before make docs solves the issue.

export LC_ALL=C
export LANG=C
export LANGUAGE=C

Hi Tristan, thanks for your report. I think the issue is Apptrainer here. I pulled the Docker image, and I can run make docs there without issues.

However, this issue just made me realize I don't build the documentation in the CI, so I will add this right away :)
