Subject: [PATCH 1/2] fix(categorize): recognise Go, Python and Ruby test files

The "testing" rule only matched JS/TS conventions (a test/spec directory
or the `.test.`/`.spec.` infix), so `foo_test.go` (Go), `test_foo.py`
(Python) and `foo_spec.rb` (Ruby) fell through to the "backend" rule and
were miscategorised. Extend the rule to also match the `_test.`/`_spec.`
suffix and the `test_` prefix, across any file extension.

Adds tests for categorize covering the new cases and guarding against
false positives such as `latest.go` and `contest.py`.
