fix(ci): filter Kokoro release check to releases with general assets (#26)

The original tag-name-only filter shipped in #24 would have flagged
`model-files-v1.1` as an upgrade candidate even though that release
ships only a Mandarin variant (`kokoro-v1.1-zh.onnx` /
`voices-v1.1-zh.bin`). Bumping engine.py URLs to it would silently
swap the multilingual model for a Chinese-focused one.

Tightens the jq filter to require both `kokoro-vX.Y.onnx` and
`voices-vX.Y.bin` assets to be present in the release before treating
it as a successor. With this in place the workflow currently resolves
`model-files-v1.0` (== pinned) and reports up-to-date, as it should.
A future general release (with non-suffixed asset names) will surface
correctly.

This was meant to land as a follow-up commit on #24 but the squash
merge captured only the first commit on that branch. Filing as its
own PR.
