Update FreeType to 2.14.1 in amazon-2

[radarhere]

The amazon-2 job has started failing - https://github.com/python-pillow/docker-images/actions/runs/18022944730/job/51284314660#step:7:284

src/_imagingft.c:1372:13: error: implicit declaration of function ‘FT_Set_Named_Instance’; did you mean ‘FT_Get_Name_Index’? [-Werror=implicit-function-declaration]
error = FT_Set_Named_Instance(self->face, instance_index);
^~~~~~~~~~~~~~~~~~~~~
FT_Get_Name_Index

This is because it is using freetype 2.8, which we no longer support. libraqm 0.10.2 was previously upgrading freetype to 2.11, but libraqm 0.10.3 switched to freetype 2.13.3 and started using the FreeType xz archive. So the error in amazon-2 is really a failure to unpack the xz archive - https://github.com/python-pillow/docker-images/actions/runs/18022944730/job/51284314660#step:6:13078
