community: Fix ConfluenceLoader load() failure caused by deleted pages (#29232)
## Description
This PR modifies the is_public_page function in ConfluenceLoader to
prevent exceptions caused by deleted pages during the execution of
ConfluenceLoader.process_pages().
**Example scenario:**
Consider the following usage of ConfluenceLoader:
```python
import os
from langchain_community.document_loaders import ConfluenceLoader
loader = ConfluenceLoader(
url=os.getenv("BASE_URL"),
token=os.getenv("TOKEN"),
max_pages=1000,
cql=f'type=page and lastmodified >= "2020-01-01 00:00"',
include_restricted_content=False,
)
# Raised Exception : HTTPError: Outdated version/old_draft/trashed? Cannot find content Please provide valid ContentId.
documents = loader.load()
```
If a deleted page exists within the query result, the is_public_page
function would previously raise an exception when calling
get_all_restrictions_for_content, causing the loader.load() process to
fail for all pages.
By adding a pre-check for the page's "current" status, unnecessary API
calls to get_all_restrictions_for_content for non-current pages are
avoided.
This fix ensures that such pages are skipped without affecting the rest
of the loading process.
