Plurality mismatch in warnings

[MarcoGorelli]

• a detailed description of the bug or suggestion
• output of pip list from the virtual environment you are using
• pytest and operating system versions
• minimal example if possible

Admittedly this is a very minor issue.

If I write a file pytest_example.py as

import warnings

warnings.warn("one warning")

and then run

pytest pytest_example.py

from the command line, the output reads

1 warnings in 0.02s

I believe this should read "1 warning in 0.02s".

Would a PR to address this be welcome?

Similarly this:

import pytest

@pytest.fixture
def fix():
    raise Exception

def test_foo(fix):
    pass

def test_bar(fix):
    pass

displays "2 error in ...s".

Those messages are generated via build_summary_stats_line in terminal.py - but I'm not sure what the best way would be to handle this, as e.g. plugins can insert their own outcomes there as well.

I think fixing our core messages is OK, so IMHO a PR would be welcome @MarcoGorelli!

Fixed in #5990 (features).
