deps: bump Minitest version to v5.26.1 and fix issues (#3144)

[minitest 5.26.0] introduced this change
minitest/minitest@68b3d0c,
and when dependabot tried to bump faker's version to 5.26.0 and we started getting this error:

```

```

I can't quite say why removing the version definition fixes this but
it seems to reuse the version we have set in the Gemfile, and the tests pass.
