Add inline to Popper props

[mathieulebasic]

Problem

When using the floating-vue component on inline text, the tooltip is not correctly positionned as shown in the screenshot below (taken from the demo)

Solution

A solution would be to add an inline props to the Popper component in order to leverage the inline() method of the floating-ui library

@Akryum I've come up with a pretty naive but functionnal approach for this. I have already made it working on my local env, I would be happy to open a PR on this projet to get it working (we love this project and highly need it now 😄 )
