gnomeExtensions: refactor update script

The update-extensions.py script downloads extension information once for each
shell version, although one extension version might be used for multiple shell
versions. To reduce the amount of downloads we first select the appropriate
extension version per shell version as done before, then download the
corresponding information once for each selected extension version, and finally
map each shell version to the downloaded information of the selected extension
version.
