build: bump version to 1.10-rc3

Man sway(5) specifies that when tiling_drag is enable, the floating_mod
can be used to drag tiling, as well as floating containers. However the
current code indiscriminately assumes any button press to be intended
for moving the container, consequently causing an unintended call to
`seatop_move_tilting:handle_button` rather than
`seatop_default:handle_button` to pass
`state=WL_POINTER_BUTTON_STATE_RELEASED` to `get_active_mouse_binding`

My idea was to make 'Handle moving a tiling container' follow the same
path as 'Handle moving a floating container' because the initial call to
handle moving a floating correctly exits that branch and ends up passing
the RELEASED state to `get_active_mouse_binding`.

Fixes #8334

(cherry picked from commit 7f1cd0b73b)
