          #
          # 1. The GitHub API documentation does not specify the order for the
          #    "list releases" endpoint, but does specify that the "latest"
          #    endpoint returns the release that points to the most recent commit.
          #    Assuming the same sort order is applied for the list endpoint
          #    (which empirically seems to hold so far), this means that they may
          #    be out-of-order wrt version numbers, e.g. 1.1.0 may appear after
          #    1.0.2.
          # 2. The `.tag_name | .[1:] | split (".") | map(tonumber)` part will
          #    turn "v1.0.2" into an array [1, 0, 2].
          # 3. jq documents its sort method to sort numbers in numeric order
          #    and arrays in lexical order (ascending in both cases).
          #
          # This is required because, while the VSCode Marketplace does show
          # _a_ version number, it doesn't handle versions at all: we can only
          # have one version on the marketplace at any given time, and any
          # upload replaces the existing version.
