depends: Freetype and xcbproto version in depends are too new

[laanwj]

While investigating interface versions for qtsowrap, i noticed that currently, in depends, the version of freetype and xproto are too new. As of 8cd9475.

At least if we're considering Ubuntu 20.04LTS as the reference. xcb-proto is even too new for 22.04LTS:

library	20.04LTS	22.04LTS	depends
libfontconfig	2.13.1	2.13.1	2.12.6
libfreetype	2.10.1	2.11.1	2.11.0 ⚠️
libxkbcommon	0.10.0	1.4.0	0.8.4
libxcb	1.14	1.14	1.14
libxcb-util	0.4.0	0.4.0	0.4.0
libxcb-image	0.4.0	0.4.0	0.4.0
libxcb-keysyms	0.4.0	0.4.0	0.4.0
libxcb-render-util	0.3.9	0.3.9	0.3.9
libxcb-icccm (=libxcb-util-wm)	0.4.1	0.4.1	0.4.1
xcb-proto	1.14	1.14	1.15.2 ⚠️

• libfreetype was upgraded from 2.7.1 to 2.11.0 in 01544dd (build: Qt 5.15.2 #23489)
• xcb-proto was upgraded from 1.14 to 1.15.2 in 7cb88c8 (depends: xcb-proto 1.15.2 #28097), apparently for a build issue

As these dependencies are used to link against existing system libraries, this means there are potential issues at runtime (though most should be caught by symbols not being found, and this hasn't been reported, so it's likely not too bad).

Edit: example of an issue caused by this: #29923 (comment)
