feat: add Pre-Translation Batch Operations support

[Copilot]

Exposes the PATCH /projects/{projectId}/pre-translations endpoint (RFC 6902 JSON Patch), allowing batch updates across multiple pre-translations in a single request.

Changes

• TranslationsApi — new batchEditPreTranslations(Long projectId, List<PatchRequest> request) method returning ResponseList<PreTranslation>
• Test fixtures — batchEditPreTranslationsRequest.json / batchEditPreTranslationsResponse.json
• TranslationsApiTest — mock registration and batchEditPreTranslationsTest for the new endpoint

Usage

PatchRequest op = new PatchRequest();
op.setOp(PatchOperation.REPLACE);
op.setPath("/status");
op.setValue("cancelled");

ResponseList<PreTranslation> result = translationsApi.batchEditPreTranslations(projectId, List.of(op));

This section details on the original issue you should resolve

<issue_title>Add support for Pre-Translation Batch Operations</issue_title>
<issue_description>The Crowdin API adds a Pre-Translation Batch Operations method: PATCH /projects/{projectId}/pre-translations. It accepts a JSON Patch document (RFC 6902) to update multiple pre-translations in one request (e.g. change status or priority). API client libraries should expose this endpoint so consumers can perform batch updates on pre-translations via the SDK.
