fix: strip branded binaries (#36641)

When creating branded release builds and using scripts/strip-binaries.py
on Linux, the final artifacts end up unstripped due to the static set of
binaries considered for stripping.
With this patch the name of the electron binary is taken from the
BRANDING.json `project_name` key.
