Description
Describe the problem
We are currently trying to add the debug support for STM32 in Arduino IDE 2.x.
We added the following to platform.txt
debug.executable={build.path}/{build.project_name}.elf
debug.toolchain=gcc
debug.toolchain.path={compiler.path}
debug.toolchain.prefix=arm-none-eabi-
debug.server=openocd
debug.server.openocd.path={runtime.tools.xpack-openocd-0.12.0-1.path}/bin/openocd
debug.server.openocd.scripts_dir={runtime.tools.xpack-openocd-0.12.0-1.path}/openocd/scripts
debug.server.openocd.script={runtime.platform.path}/variants/{build.variant}/{build.openocdscript}
An openocd.cfg file was added in each variant directory and a the boards.txt looks like this

With the above configuration, if we run a compilation for Nucleo F030R8, it works as expected, but if we try to debug we have the following message:

As we can see, the {build.variant} is not properly expanded to our STM32F030 but to a STM32C0 which is the first to appear in the boards.txt after the declaration of the build.openocdscript
To reproduce
Use code from stm32duino/Arduino_Core_STM32#1976 and try debugging a Nucleo that is not the first in its category.
Expected behavior
{build.variant} should be expanded with the correct value so that we could debug.
