/**
 * Sanitized rule 'prefer-optional-chain' from TypeScript ESLint.
 *
 * TypeScript ESLint's rule raises a runtime error if the parser services of the
 * injected context is missing some helper functions allowing to convert between
 * TypeScript ESLint and TypeScript ASTs. Contrary to rules requiring type checking,
 * there is no way to determine programmatically if a rule requires such a service.
 *
 * This is the case for the rule 'prefer-optional-chain', for which we need to provide
 * a custom sanitization in case the parser services miss these helpers.
