Add support for updateOption parameter in string editing endpoints

[andrii-bodnar]

The Crowdin API adds a new optional updateOption query parameter to the source string editing endpoints: Edit String (PATCH /projects/{projectId}/strings/{stringId}) and String Batch Operations (PATCH /projects/{projectId}/strings).

The parameter defines whether existing translations and approvals are kept when a string is updated, and is applied only when text or identifier is changed. Allowed values:

• keep_translations_and_approvals (default)
• keep_translations
• clear_translations_and_approvals

API client libraries should be updated to expose updateOption on these endpoints so consumers can control translation/approval retention when editing strings via the SDK.

• String Batch Operations
