[Python2 Runtime] Release 4.10 breaks support for Python 2.7 - antlr4-python2-runtime 4.10 leading f in setup.py for python2

[Лапоть]

Hello, 

new version(4.10) of antlr4-python2-runtime is broken cause of leading f in setup.py for python2 

pip2 install antlr4-python2-runtime
DEPRECATION: Python 2.7 reached the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 is no longer maintained. pip 21.0 will drop support for Python 2.7 in January 2021. More details about Python 2 support in pip can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support pip 21.0 will remove support for this functionality.
Defaulting to user installation because normal site-packages is not writeable

maybe it could be fixed via changing it to
