### Bug description

Dropbox URL is change from June 2023.
Please someone tell me how to embed the video to website.
This is the link.
https://www.dropbox.com/scl/fi/4vrzdjnk7i0wuihl3pzud/Video.mp4?dl=0&rlkey=6ckf190r0jiljtnech4bym1b0


### Steps to reproduce

- Upload a video to dropbox
- Copy the Share URL `https://www.dropbox.com/s/s7cffdll62ojsy1/local-video.mp4?dl=0`
- Use the video shortcode to load this mp4 via VideoJS
`{{< video https://www.dropbox.com/s/s7cffdll62ojsy1/local-video.mp4?dl=0 >}}`

### Expected behavior

- As before the video loads via the VideoJS snippet.

### Actual behavior

- The video doesn't load and shows a `The media could not be loaded, either because the server or network failed or because the format is not supported.` error.

### Your environment
