Resolving addresses doesn't seem to work for `flash --monitor` anymore

[bjoernQ]

But it might still work with the monitor command (and supplying the correct ELF)

Observed with 56a23a7 but most probably this problem was present even before (but works fine on v3.3.0)

[bugadani]

Okay I thought this would be an easy fix, but alas, no. Monitoring a debug elf works as expected, but a --release firmware's addresses are not resolved.

[bugadani]

And for me, even the older espflash doesn't resolve addresses, so I'm not sure this is an espflash bug.

    GPIO interrupt

     This prints "Interrupt" when the boot button is pressed.
     It also blinks an LED like the blinky example.

     The following wiring is assumed:
     - LED => GPIO2
     - BUTTON => GPIO0 (ESP32, ESP32-S2, ESP32-S3) / GPIO9

And espflash monitor --elf examples\target\riscv32imac-unknown-none-elf\release\gpio_interrupt shows the same - so it's not about flash --monitor vs monitor
