fix for recent builds

[tube0013]

I ran into build issues on my fork recently, even when trying to build off of something that previously built fine.

it was not finding the project path after the project generation:

After a bunch of trial and error I fixed this by adding the full path to the export-destination in the slc generate command:

          slc generate \
              --with="${{ inputs.device }},${{ inputs.components }}" \
              --project-file="${{ inputs.project_file }}" \
              --export-destination="/__w/silabs-firmware-builder/silabs-firmware-builder/${{ inputs.firmware_name }}" \
              --copy-proj-sources --copy-sdk-sources --new-project --force \
              --configuration="${{ inputs.configuration }}"

adding the /__w/silabs-firmware-builder/silabs-firmware-builder/ in front of the firmware_name.

I think github may have changed something, I'd do a pr but my github abilities can't get it in a form of just this single change.

This was probably caused by an slc update bug?.

I expect you can probably just prepend with $PWD
