/**
 * Extracts the name of a decorator from its AST node.
 *
 * Processes the decorator text to extract just the name portion, removing the
 * '@' prefix if present and any parameters or arguments that follow the name.
 * This is useful for sorting and matching decorators by their base name.
 *
 * @example
 *
 * ```ts
 * // Simple decorator
 * getDecoratorName({ sourceCode, decorator: @Component });
 * // Returns: 'Component'
 * ```
 *
 * @example
 *
 * ```ts
 * // Decorator with parameters
 * getDecoratorName({ sourceCode, decorator: @Injectable({ providedIn: 'root' }) });
 * // Returns: 'Injectable'
 * ```
 *
 * @example
 *
 * ```ts
 * // Namespaced decorator
 * getDecoratorName({ sourceCode, decorator: @angular.Component() });
 * // Returns: 'angular.Component'
 * ```
 *
 * @param params - Parameters object.
 * @param params.sourceCode - ESLint source code object for text extraction.
 * @param params.decorator - Decorator AST node to extract name from.
 * @returns The decorator name without '@' prefix and parameters.
