Add Japanese translation to the GitHub Copilot workshop

[SIkebe]

This PR introduces a Japanese translation for the GitHub Copilot workshop.

There’s one point that needs clarification: For the translated filename, should we use the language code such as ja, or the country code like jp?
The CONTRIBUTING.md states:

Add translations

You can localize any workshop in this repository by creating a new folder translations in the same directory as the original folder, and naming any translated file <original_name>.<country_code>.<extension>.
For example, the French translation of workshop.md would be translations/workshop.fr.md.

You can follow the same rule if you need to localize any asset, for example assets/image.png should be localized to assets/translations/image.fr.png.

However, I’ve noticed that various documents in this repository suggest using the language code. Could you please confirm which is correct?

FYI, I published GitHub Pages so that you can review the translated workshop page.

Thank you! Using language code here is fine.
If the original assets (images/code) were not updated, could you update the links to point to the original one instead of duplicating them inside the /translations/ subfolder?

Then, should I fix the CONTRIBUTING.md?

When I use relative links, the assets were not displayed and you can't download the assets zip file. So I copied those assets into the /translations/ subfolder.

Which url should we use to show the assets on translated page locally and on GitHub Page?

Hi @sinedied
Do you have any opinions or advice regarding the above issue?

[sinedied]

Hi @SIkebe and thank you for your patience.
You're right it seems there's an issue when using ../assets, I'll open an issue and fix it as soon as possible.
Keep in mind it may take 1-2 weeks as it's a very busy period, again I thank you for your contribution and patience.

[SIkebe]

Thank you for confirming! Once the issue is resolved, I'll check that again.
