Using s3 range request with localstack causes incorrect content type to be returned & some metadata to be missing:
To reproduce, put object:
`aws s3api put-object --endpoint http://localhost:3006 --bucket some-bucket --key some-dir/some-key --body text.txt --content-type text/plain --content-language en-US --cache-control no-cache`

And compare regular request vs range one:
`aws s3api get-object --endpoint http://localhost:3006 --bucket some-bucket --key some-dir/some-key output.txt --range bytes=0-3`
`aws s3api get-object --endpoint http://localhost:3006 --bucket some-bucket --key some-dir/some-key output.txt`

This works correctly (returns the same metadata regardless of using `--range bytes=0-3`) on aws s3.

Also:
Getting object with/without `range bytes=0-3` should return header "AcceptRanges: bytes" but it doesn't.
