Uncaught Error: net::ERR_NETWORK_IO_SUSPENDED (and other node:net errors)

These only happen on linux

woke computer from suspend mode, error message was present on screen

this one should probably be safe to let the request fail and try again, similar to #5336

Test Notes

it should be enough to test this on linux.

• you will need a fixed test version of the desktop client that already has an update it can download

• you will also need an affected version of the desktop client ( =< 3.112.7)

• before each test, copy the executables (they overwrite themselves with the update)

• use the affected version to find a setup that causes the error while the terminal is showing the differential update download (slow down network to 0, pull cable, switch from wired to wifi, turn off VPN, reset router...)

• do the same with the fixed version

• no uncaught errors are visible and the update eventually succeeds

Regressions

• update still works on windows
• update still works on mac

I'd say convert to offline error

These are probably caused by this: electron-userland/electron-builder#2398
