docs: Use a PEP440-compliant version constraint in pip-compile documentation

[TheMrMilchmann]

Changes

Updates the example in the documentation of the pip-compile manager to declare a Python version constraint using a PEP440-compliant format.

Context

Using a Python version as suggested in the docs causes the pip-compile invocation to fail. Note, that this is especially annoying as it is not detected as a configuration error by Renovate. (I assume that the constraint is not validated.)

Relevant log excerpt of a failed run:
