fix(ci): use the platform-specific catalog draft path when submitting

The "Submit catalog draft" step was hardcoded to
dist/plugin-release/catalog-draft.json, which only exists for the job
whose PLUGIN_PLATFORM_SUFFIX is empty (previously always windows-x64,
since it was the only job allowed to submit). Now that every platform
submits, non-primary platforms actually write to
catalog-draft-<suffix>.json and the hardcoded path failed with ENOENT.
Use $env:CATALOG_DRAFT_PATH, which the "Generate catalog draft metadata"
step already exports correctly and which "Upload metadata to release"
already relies on.
