feat: add List Supported AI Provider Models support

[Copilot]

Adds client support for the new List Supported AI Provider Models endpoints, which return enriched model metadata (capabilities, pricing, modalities, etc.) across all configured providers — as opposed to the existing per-provider model listing.

New methods

• listAiOrganizationSupportedProviderModels(options?) → GET /ai/providers/supported-models (Enterprise)
• listAiUserSupportedProviderModels(userId, options?) → GET /users/{userId}/ai/providers/supported-models (Crowdin)

Both accept optional providerType, enabled, and orderBy filters via a new ListSupportedProviderModelsOptions type.

New types

• AiSupportedProviderModelResponse — full response schema including displayName, supportReasoning, intelligence, speed, price, modalities, contextWindow, maxOutputTokens, knowledgeCutoff, releaseDate, features
• ListSupportedProviderModelsOptions — extends PaginationOptions with providerType: ProviderType, enabled: boolean, orderBy: string

Usage

// Enterprise
const models = await crowdin.ai.listAiOrganizationSupportedProviderModels({
  providerType: 'open_ai',
  enabled: true,
});

// Crowdin
const models = await crowdin.ai.listAiUserSupportedProviderModels(userId, {
  providerType: 'google_gemini',
  orderBy: 'intelligence desc',
});
