[PWGLF] Remove the OO 5.36 TeV variants of the ML injection configs

generator_pythia8_LF_rapidity_width.C builds the underlying event in a separate Pythia object, while
GeneratorPythia8::updateHeader reads the heavy-ion information of the base object, which never
generated an event: o2-sim crashes in getNcoll with the Angantyr OO configuration (the existing
GeneratorLF_ResonancesBaryonic_OO_injection.ini crashes in the same way). To be revisited once the
macro handles heavy-ion backgrounds.
