Do not list not installed packages in mne.sys_info() #11543
Description
We would like to see the output of mne.sys_info() in issue reports, but this list is very long – even when many packages are not installed it looks like this:
Platform: macOS-13.2.1-arm64-arm-64bit
Python: 3.10.10 (v3.10.10:aad5f6a891, Feb 7 2023, 08:47:40) [Clang 13.0.0 (clang-1300.0.29.30)]

I propose to exclude packages that are not installed, so the list would be much shorter:
