fix(docs): correct package names in FeatureTables.js (#32377)

## **Description:** 
Updated incorrect package names in `FeatureTables.js` by replacing
underscores with hyphens to reflect their actual names on PyPI. This
aligns with the actual PyPI package names and prevents potential
confusion or installation issues.

The following package names were corrected:
- `langchain_aws` ➝ `langchain-aws`
- `langchain_community` ➝ `langchain-community`
- `langchain_elasticsearch` ➝ `langchain-elasticsearch`
- `langchain_google_community` ➝ `langchain-google-community`

 
## **Issue:** N/A
## **Dependencies:** None
## **Twitter handle:** N/A
