Move and enhance python API grammar tests (#6538)

The existing test for python API grammar is moved to the right location, `yapf`ed, and changed according to the new style of python API tests. Additionally, minor changes are introduced in order to be an exact translation of https://github.com/cvc5/cvc5/blob/master/test/unit/api/grammar_black.cpp
