Nitpick: Clarify that number reported is number of passed tests, not total tests

[rradczewski]

TL;DR: Changes "tests" to "passed" to explain that the number represents the number of passed tests, not overall tests.

I know this is an incredible nitpick, but I'm using the human-readable output of gleeunit to verify that my starter project still works correctly. For v1.4.0 (v1.3.1...v1.4.0), the output changed from counting the total number of tests to counting the number of passed tests:

Example:

https://github.com/rradczewski/kata-bootstraps/blob/main/gleam/test/bootstrap_test.gleam with gleeunit 1.3.1:

...
Failures:

  1) bootstrap_test.failing_test
     Values were not equal
     expected: True
          got: False
     output: 

Finished in 0.010 seconds
2 tests, 1 failures

With gleeunit 1.4.0 and later:

...
 info: 
False
should equal
True

1 tests, 1 failures

The old implementation was here:

gleeunit/src/gleeunit_progress.erl

Line 427 in dee7bf6

Text = io_lib:format("~p tests, ~p failures~ts~ts~n", [Total, Fail, SkipText, CancelText]),

For reference, here's an overview of other testrunners and how their human-readable report looks like: https://github.com/search?q=repo%3Arradczewski%2Fkata-bootstraps+%22failingTestVerification%22&type=code
