win build: bump wine 6.0.2->7.0.0.0 to fix installing python

with wine 6.0.2 and 6.0.3, cpython 3.9.11 fails to install (but cpython 3.9.10 worked)
```
010c:err:virtual:virtual_setup_exception stack overflow 1220 bytes in thread 010c addr 0x7bc6713d stack 0x440b3c (0x440000-0x441000-0x640000)
🗯 ERROR: wine msiexec failed for dev.msi
🗯 ERROR: prepare-wine failed
```

-----

btw, related note:
After changing the Dockerfile, building the docker image from cache failed. Setting ELECBUILD_NOCACHE=1 fixed it:
```
E: Could not configure 'libc6:i386'.
E: Could not perform immediate configuration on 'libgcc-s1:i386'. Please see man 5 apt.conf under APT::Immediate-Configure for details. (2)

$ ELECBUILD_NOCACHE=1 ./contrib/build-wine/build.sh
```
