Add localization (l10n) support

We should consider adding **localization (l10n)** support to our VS Code extension to make it easier to translate into multiple languages and provide a better experience for non-English users.

#### Reference Implementation

Microsoft provides an official example demonstrating how to implement localization in a VS Code extension:

#### Notes

- We plan to display data from the **compatibility tables**, which currently include only English descriptions. This limitation should be taken into account when implementing localization — or we should consider adding localization support to the compatibility tables as well.
- The error messages provided by the linter are also available only in English.
- We could also consider using **Crowdin** to manage translations and streamline the localization workflow.
