Migrate membership section's voting pages to Hugo

This issue was created to decide whether to migrate to Hugo, deprecate/archive, or delete the pages (with or without a redirect).

None of these pages are useful as the elections have already concluded. Is there any value in keeping them? The pages in question are:

vote2008

• https://www.eclipse.org/membership/vote2008/index.php
• https://www.eclipse.org/membership/vote2008/vote.php (this one could definitely be deleted)

vote2011

• https://www.eclipse.org/membership/vote2011/index.php

vote2019

• https://www.eclipse.org/membership/vote2019/index.php

vote2020

• https://www.eclipse.org/membership/index.php
