fix(ci): name rolling release packages after the branch, not the version number

The install page (<https://www.mrdocs.com/docs/mrdocs/install.html>)
reads the rolling-release assets via the GitHub API and picks one per
platform by filename suffix. Because each develop push named its
packages with the current project version (e.g.
MrDocs-0.8.0-Linux.tar.gz), a version bump produced a new filename and
left the previous version's files behind as stale assets on the
develop-release and master-release rolling releases. The first-match
lookup then happily returned the wrong (older) asset.

Thus, for non-tag publishes, rename each package from

    MrDocs-<semver>-<platform>.<ext>

to

    MrDocs-<ref-name>-<platform>.<ext>

right before the upload step. Subsequent pushes to the same branch now
produce identical filenames, which action-gh-release overwrites in
place. Tag releases, which are immutable per version, keep their
versioned filenames unchanged.

The upload glob is relaxed from `MrDocs-*.*.*-*.*` to `MrDocs-*-*.*` to
accommodate the branch-named form.

A one-time manual cleanup of legacy versioned assets on the existing
develop-release and master-release rolling releases is still required;
subsequent CI runs will keep the state clean on their own.
