Add MIME types for PPT and PPTX files (#12562)

Browse Source 
Otherwise, slide files cannot be opened in Chat module

### What problem does this PR solve?

Backend Reason (API): In the api/utils/web_utils.py file of the backend,
the CONTENT_TYPE_MAP dictionary is missing ppt and pptx.
MIME type mapping. This means that when the frontend requests a PPTX
file, the backend cannot correctly inform the browser that it is a PPTX
file, resulting in the file being displayed incorrectly.
Type identification error.
