fix(ci): correct glob pattern for finding downloaded release assets

The `create-release` job was failing to attach assets to the GitHub
Release because the `files` glob pattern was incorrect.

When `actions/download-artifact@v4` downloads multiple artifacts without
a specific name (as used in this job), it places each artifact's contents
into a subdirectory named after the artifact within the specified `path`
(e.g., `release-assets/release-asset-x86_64-unknown-linux-gnu/`).

The previous glob pattern `release-assets/*` matched these subdirectories,
but the `softprops/action-gh-release` action requires paths to the actual
files to be uploaded.

This commit changes the glob pattern to `release-assets/*/*`, which
correctly finds the archive files (`.tar.gz`, `.zip`) located *inside*
the subdirectories created by the download step, allowing them to be
successfully attached to the release.
