Tidy up comments by removing several cases of duplicated words (#4175)

chore: remove duplicate words in five comments

All comment-only fixes.

- desktop/src/window/win/native_handle.rs L228: "Return 0 to to tell Windows" -> "Return 0 to tell Windows"
- node-graph/libraries/vector-types/src/vector/algorithms/spline.rs L24: "is the the second point" -> "is the second point"
- node-graph/libraries/vector-types/src/vector/algorithms/poisson_disk.rs L153: panic message "couldn't be be mapped" -> "couldn't be mapped"
- node-graph/libraries/rendering/src/renderer.rs L1800: "this is is achived" -> "this is achieved" (also fixes "achived")
- editor/src/messages/tool/common_functionality/shapes/shape_utility.rs L494,523: "Check if the the cursor" -> "Check if the cursor"
