Describe the bug
When you add an inline image, there isn't a way to replace it with a new image.

To reproduce
Steps to reproduce the behavior:

1. Go to the editor and add some text.
2. Click on the dropdown arrow and click "Inline image"
3. Upload or select an image
4. Click on the image; you can change its size, but not replace the image.

Expected behavior
I expect inline images to have a similar block toolbar as images, or, image settings should be appended to the paragraph/heading toolbars.

Screenshots

Editor version (please complete the following information):

• WordPress version: 5.5.1
• Does the website has Gutenberg plugin installed, or is it using the block editor that comes by default?: Default
