[sam2][demo][1/x] Fix file upload

[raedle]

Summary:

The Strawberry GraphQL library recently disabled multipart requests by default. This resulted in a video upload request returning "Unsupported content type" instead of uploading the video, processing it, and returning the video path.

This issue was raised in #361. A forward fix is to add multipart_uploads_enabled=True to the endpoint view.

Test Plan:

Tested locally with cURL and upload succeeds

Request

curl http://localhost:7263/graphql \
  -F operations='{ "query": "mutation($file: Upload!){ uploadVideo(file: $file) { path } }", "variables": { "file": null } }' \
  -F map='{ "file": ["variables.file"] }' \
  -F [email protected]

Response

{"data": {"uploadVideo": {"path": "uploads/<HASH>.mp4"}}}

Thanks for the fix!

Should we also update the Strawberry version in setup.py to be "strawberry-graphql>=0.243.0"? (Otherwise the multipart_uploads_enabled parameter might not be available since it's newly introduced in strawberry-graphql/strawberry@37265b2, and users might get an error if they are running an older version of strawberry-graphql)

(I think we can either use a loose version of "strawberry-graphql>=0.243.0" or pin it to a strict version like "strawberry-graphql~=0.246")

Looks good to me, and adding a minor comment about the version in setup.py.
