161 use json instead of popot files for translations

[AlixANNERAUD]

This pull request migrates application localization files from the legacy .po/.pot format to modern .json files for both the settings and shell command line modules, and introduces improvements to formatting and CI configuration. The main changes include replacing .po/.pot translation files with equivalent .json files, updating formatting tasks to include JSON files, and making minor improvements to CI and documentation build scripts.

Localization migration and improvements:

• Replaced all .po and .pot translation files for the settings module (executables/settings/locales/en/messages.po, executables/settings/locales/fr/messages.po, executables/settings/locales/messages.pot) with equivalent en.json and fr.json files using a flat key-value structure. This modernizes localization and simplifies translation workflows. [1] [2] [3] [4] [5]
• Replaced the .po translation file for the shell command line module (executables/shell/command_line/locales/en/messages.po) with a new en.json translation file. [1] [2]

Formatting and build improvements:

• Added a new format-json task to the Makefile.toml using Prettier to format all JSON files, and updated the main format task to include this step.
• Updated the documentation build step in .github/workflows/deploy.yml to copy the full guest documentation directory, not just the guest subdirectory, improving the completeness of published docs.

Miscellaneous:

• Fixed the case of the Cargo package ecosystem in .github/dependabot.yml to cargo for consistency and correctness.
