docs: fix return type of setJumpList() in electron.d.ts (#33964)
Before:
```ts
setJumpList(categories: (JumpListCategory[]) | (null)): void;
```
After:
```ts
setJumpList(categories: (JumpListCategory[]) | (null)): ('ok' | 'error' | 'invalidSeparatorError' | 'fileTypeRegistrationError' | 'customCategoryAccessDeniedError');
```
