Subject: [PATCH] [CELEBORN-905] Redraw the flowchart backpressure.svg after
 worker pause logic is reconstructed

### What changes were proposed in this pull request?
Add a new `backpressure.svg` to replace the out-date one.

### Why are the changes needed?
After #1811, we refactor celeborn worker back-pressure logic, we should add new flowchart for user to understand.

### Does this PR introduce _any_ user-facing change?
Yes

### How was this patch tested?

![backpressure](https://github.com/apache/incubator-celeborn/assets/52876270/34f3f4b8-28cf-4cce-88a4-e6fee1886d94)
