[Feature]: Change dock position
### What's the feature?

I see that this feature has been previously requested and coded (https://github.com/tldraw/tldraw/pull/774). But it doesn't seem that it made it into the main branch. Please correct me if I am wrong. 

It would be really nice to have this feature on tablets. The dock's position at the bottom of the screen results in a lot of inadvertent palm touches. Is there a reason this feature isn't in the main branch?
