[UMBRELLA ☂️] chore: expand Language Support (`i18n`) for Better Global Accessibility

[brionmario]

Important

Contributors for this task should be native speakers or have professional fluency in the target language to ensure accurate, culturally appropriate translations.

Note

This issue can be taken by multiple contributors!
Please comment below with the language you would like to contribute with.

Current Limitation

Currently, the Asgardeo JavaScript SDK only supports English 🇺🇸 by default. We need to add comprehensive language support to improve internationalization coverage for React UI components.

🌍 How to Contribute

To contribute a language:

1. Comment below with the language you'd like to contribute (e.g., "I'd like to contribute Spanish translations")
2. We'll assign you to that specific language in the table below
3. You can work on your language independently

Hi @brionmario I’d like to reserve this issue and contribute Spanish (es-ES) translations. Please assign me to this language. I’ll update the @asgardeo/i18n package with accurate translations and ensure everything works as expected.

Hi @brionmario 👋,

I’d like to contribute Sinhala (සිංහල - si-LK) language support for the Asgardeo React SDK.

Package: @asgardeo/react

• ✅ I am a native speaker of Sinhala and can provide accurate, culturally appropriate translations.
• ✅ I will follow the suggested implementation plan and add a new locale file under packages/javascript/src/i18n/si-LK.ts.
• ✅ I will ensure the language pack integrates properly with the usage pattern and update the documentation as needed.

Please assign me Sinhala (si-LK) in the language support table, and I’ll start working on it 🚀

Thanks!
