Properly redirect URLs of "old" typo3.org website

Some examples:

• https://typo3.org/news/article/typo3-cms-7622-and-875-released/ (404 currently)
• https://typo3.org/teams/security/security-bulletins/typo3-core/typo3-core-sa-2017-004/ (redirected to "Teams and Committees" currently)

At least for releases and security advisories it's pretty important, that distributed links are available. This affects linked references in security databases and serve as main reference for our main product: TYPO3 CMS
