[py 3.13t] Fix for vision nightly failure on MacOS M1 machines (#6358)

Follow up after:
#6242

Newer conda is having trouble installing py3.13t artifacts, please see:

Could not solve for environment specs
The following packages are incompatible
├─ libpng =* * is installable with the potential options
│  ├─ libpng 1.6.37 would require
│  │  └─ zlib >=1.2.11,<1.3.0a0 *, which can be installed;
│  └─ libpng 1.6.39 would require
│     └─ zlib >=1.2.13,<1.3.0a0 *, which can be installed;
└─ python-freethreading =* * is not installable because it requires
   ├─ cpython =3.13.2 *, which requires
   │  └─ python =3.13.2 * with the potential options
   │     ├─ python 3.13.2 would require
   │     │  └─ libzlib >=1.3.1,<2.0a0 *, which requires
   │     │     └─ zlib ==1.3.1 *_2, which conflicts with any installable versions previously reported;
   │     └─ python 3.13.2, which can be installed;
   └─ python_abi =* *_cp313t, which requires
      └─ python =3.13 *_cp313t, which conflicts with any installable versions previously reported.
```

As a consequence vision is compiled without png support and failing
