Release tags not being created automatically

The [v1.54c](https://github.com/imagej/ImageJ/releases/tag/v1.54c) tag was not created automatically and had to be tagged manually.

Presumably, the [v1.54b](https://github.com/imagej/ImageJ/releases/tag/v1.54b) tag was created automatically as appropriate.

Looking at the [action history](https://github.com/imagej/ImageJ/actions) and [build script](https://github.com/scijava/scijava-scripts/blob/main/ci-build.sh) I can't tell what machinery is actually supposed to create these tags.

Start by comparing the v1.54b and v1.54c release entries with the linked action history, then trace the relevant logic in scijava-scripts/ci-build.sh. Determine which workflow is supposed to create release tags and verify that a future release produces its tag automatically rather than requiring manual tagging.
