Add localization for autocomplete fields

[csh-tech]

Description

After adding the filament-language-switch plugin, I noticed that the autocomplete field labels and placeholders remained in English regardless of the selected language.

I thought it would be beneficial to add autocompleteLabel and autocompletePlaceholder as default keys in the language files to support automatic localization.

Changes

Added two new translation keys to enable automatic translation based on the application's locale:

'autocomplete.label' => 'Address',
'autocomplete.placeholder' => 'Search for an address...',

These keys integrate with Filament's existing localization system, allowing the field to automatically display labels and placeholders in the user's language.

Usage Example

GoogleAutocompleteField::make('address')

This will automatically display all text in the application's current locale without any additional configuration.

Benefits

• Eliminates the need to manually set translated strings for each language
• Ensures consistency with Filament's localization patterns
• Works seamlessly with language switcher plugins
