fix(borders): maximize compat w/ komorebi impl

This commit ensures that the "Komorebi" border implementation is set as
the default as it has the maximum range of compat across different
Windows versions, whereas the "Windows" implementation requires Win 11.

Because "Windows" implementation methods will error on Windows 10,
restore_all_windows has been updated to only attempt to remove accents
if BorderImplementation::Windows is selected (this is gated behind the
WINDOWS_11 check).
