docs: remove unicode string form in rdflib/term.py (#2384)
The use of Unicode literals is an artefact of Python 2 and is incorrect in Python 3. Doctests for docstrings using Unicode literals only pass because [ALLOW_UNICODE](https://docs.pytest.org/en/7.1.x/how-to/doctest.html#using-doctest-options) is set, but this option should be disabled as RDFLib does not support Python 2 any more. This partially resolves <#2378>. Signed-off-by: Alex Nelson <[email protected]>
