feat: add locale to plant module

[mayank-Pareek]

This PR introduces locale support in the plant module, with enUS set as the default.

Fixes Issue: #898

Changes:

1. Locale Parameter for Plant Definitions
   • Added getPlantDefinition() with locale as parameter to support locale-based plant data.
   • Defaulted to enUS as a fallback for undefined or unsupported locales:

   const struct PlantDefinition& getPlantDefinition(Locale locale) {
      switch (locale) {
       default:
           return enUSPlantDefinition;
       }
   }

2. Locale-Specific Naming in Plant Data
   • Updated array naming for plant data, to reflect the locale:

   const auto enUSTrees = std::to_array<std::string_view> {/* data */};

3. Test Suite Updates
   • Updated plant_test to incorporate the new locale parameter.

---

• Ran all unit tests after building project to ensure no breakage from the locale addition.
