community: Corrected aload func to be asynchronous from webBaseLoader (#28337)

- **Description:** The aload function, contrary to its name, is not an
asynchronous function, so it cannot work concurrently with other
asynchronous functions.

- **Issue:** #28336 

- **Test: **: Done

- **Docs: **
[here](e0a95e5646/docs/docs/integrations/document_loaders/web_base.ipynb (L201))

- **Lint: ** All checks passed
