Adjust F541 linting issue on Lib/test module

[rodolfomp123]

Feature or enhancement

After running ruff in CPython, some linting and formatting errors were found.
This issue intends to fix the F541 f-string without any placeholders errors related to the Lib/test module.

Pitch

In the CPython/Lib directory, we run the following command:

ruff test/ --select F541

We can see these kind of alerts:

...
test/test_sqlite3/test_regression.py:494:32: F541 f-string without any placeholders
test/test_sqlite3/test_regression.py:501:32: F541 f-string without any placeholders
