fix(treesitter): find buffer in multiple windows
Problem:
1. When interacting with multiple :InspectTree and the source buffer
   windows there is a high chance of errors due to the window ids not
   being updated and validated.
2. Not all InspectTree windows were closed when the source buffer was
   closed.

Solution:
1. Update InspectTree window id on `CursorMoved` event and validate
   source buffer window id before trying to navigate to it.
2. Close all InspectTree windows
