Issue 49156 - Modify token :assert: to :expectedresults:
Description: In order to import the test cases from source code to Polarion,
we are using betelgeuse and betelgeuse uses :expectedresults: token in place
of :assert: token. That needs a fix in create_test file and all other files
which used :assert: in docstrings
