In the Rails repository we use a `bin/test` executable to run our tests.
However the rerun snippets still included `bin/rails test`:
BEFORE:
```
Failed tests:
bin/rails test test/cases/adapters/postgresql/schema_test.rb:91
```
AFTER:
```
Failed tests:
bin/test test/cases/adapters/postgresql/schema_test.rb:91
```
This adds a script `bin/test` to most Rails framework components. The
script uses the rails minitest plugin to augment the runner.
See https://github.com/rails/rails/pull/19571 for details about the
plugin.
I did not yet add `bin/test` for activerecord, activejob and railties.
These components rely on specific setup performed in the rake-tasks.
