Add .mo and .json files for translations

[frenzymadness]

See the discussion in #6717

Shipping just .po files is useless because users would need to generate .mo files from them to make the translation work. Much better would be to update the release process to make this automatic, regenerate .mo and .json files, and remove .po files when building the wheel but because notebook v 7 will use a different system with language packs (where this automation is implemented) it does not really make sense to make this fix more complicated than it is.

I know that the .mo files are binary and therefore not good for being tracked in the git but this seems to be acceptable as a short term solution for notebook 6.

Also, the files were for some reason ignored via .gitignore file but nl translation has them.

👍 for the suggestion

For information, in the language packs repo mentioned, we did version the .mo and .json files up to recently.

I tried out the translations and from what I could cross-reference with a translator, it looked good!
@echarles is this something that could be included in the next release of 6.5?

[echarles]

@RRosio Sure, Let's get that merged before cutting a new 6.5

[echarles]

I have checked notebook/i18n/fr_FR/LC_MESSAGES/nbjs.json and it looks good. Well, noyau is the literate translation of kernel and I have always found weird those kind of translation... The sentence Le noyau semble planté is a bit weird also, but just acceptable. The rest looks OK.

Why is the notebook/i18n/nl/LC_MESSAGES/nbjs.json not included in this PR? I could have a look also, my dutch is basic but ok.

Any Russian, Japan or Chinese language skills around?

Will this need to be ported to NbClassic?

I believe for dutch the notebook/i18n/nl/LC_MESSAGES/nbjs.json is already present

Unfortunately I personally can't provide much feedback on the different languages included in this PR...

Will this need to be ported to NbClassic?

Yes I believe a PR would also need to be submitted to make these files available for nbclassic.

I'll regenerate the files and open a PR there as well.

Correction. This is not needed for nbclassic because the build process does it.

• .mo files are generated in https://github.com/jupyter/nbclassic/blob/51b475bdf94e01ce84913800b19559eaf49a7d24/setupbase.py#L337
• .json files are generated in https://github.com/jupyter/nbclassic/blob/51b475bdf94e01ce84913800b19559eaf49a7d24/setupbase.py#L559

There is only one small bug I'm gonna report or fix but the .mo and .json files are already present in the sdist and wheel.

Suggested change

	"kernel と通信できません"
	"カーネルと通信できません"

Consistent styling of "kernel" with commands below

[frenzymadness]

Thanks for the proposal but this file is generated from the nbjs.po source file so the change should be proposed to that file and nbjs.json can be regenerated then, see

notebook/notebook/i18n/ja_JP/LC_MESSAGES/nbjs.po

Line 155 in d0ecb74

msgstr "kernel と通信できません"
