python3-rdflib: upgrade 5.0.0 -> 6.0.0

-License-Update: Copyright year updated to 2021.

2021/07/20 RELEASE 6.0.0
========================
6.0.0 is a major stable release that drops support for Python 2 and Python 3 < 3.7. Type hinting is now present in much
of the toolkit as a result.

It includes the formerly independent JSON-LD parser/serializer, improvements to Namespaces that allow for IDE namespace
prompting, simplified use of `g.serialize()` (turtle default, no need to `decode()`) and many other updates to
documentation, store backends and so on.

Performance of the in-memory store has also improved since Python 3.6 dictionary improvements.

There are numerous supplementary improvements to the toolkit too, such as:

* inclusion of Docker files for easier CI/CD
* black config files for standardised code formatting
* improved testing with mock SPARQL stores, rather than a reliance on DBPedia etc
