Content: System Requirements dont match latest LTS/ mayor release

• The page "System Requirements" does not list the requirements of the latest TYPO3 LTS or mayor version
• The page "Download TYPO3" does not list correct system requirements for each version

Eg.:

• https://typo3.org/cms/requirements/ "Middleware: PHP 5.5 or later" → not supported in TYPO3 8
• https://typo3.org/cms/requirements/ "Hardware: At least 256 MB of RAM" → TYPO3 8 & 9 list 128M (sidenote: I agree, that 256 MB minimum looks more reasonable to me)
• https://typo3.org/cms/requirements/ Link to detailed installation instructions broken (https://git.typo3.org/Packages/TYPO3.CMS.git/blob/HEAD:/INSTALL.md%C2%A0) → use https://docs.typo3.org/typo3cms/InstallationGuide/In-depth/SystemRequirements/Index.html or https://github.com/TYPO3/TYPO3.CMS/blob/TYPO3_8-7/INSTALL.md instead
• https://typo3.org/cms/requirements/ The page should list the TYPO3 version, which was used as reference/source for this table
• https://get.typo3.org/ "TYPO3 8: MySQL 5.5" → MySQL 5.7 is supported as well
• https://get.typo3.org/ "TYPO3 8: PHP 7" → should be "PHP 7.0 or later" or "PHP 7.0, 7.1, 7.2"
