get-pip.py for Python 3.5

Since yesterday’s release of pip 21.0, get-pip.py no longer supports Python 3.5 due to using f-strings:

Traceback (most recent call last):

SyntaxError: invalid syntax

Could a /3.5/get-pip.py be added, analogous to the 3.4 and older versions?

@anetanel The site will update when this PR by @pradyunsg will be merged In the meantime you can use 3.4 instead and see if that works, just point your CI to https://bootstrap.pypa.io/3.4/get-pip.py

@danielfm Everything got moved around due to #61. The URL is now https://bootstrap.pypa.io/pip/3.5/get-pip.py.
