Describe the bug
Images are always inserted with a width of 512px.

To Reproduce

• open a blocknote editor with an empty content
• create a small (e.g., 30x30px) image locally
• insert an image block, upload the small image
• observe the image

Expected:

• the image is 30x30px
  Actual
• the image is resized to 512px, leady to badly upscaled and pixalted images

Misc

• I'm a sponsor and would appreciate if you could look into this sooner than later 💖
