MD5 no longer part of release process

It was a nail-biter of a vote, but MD5 removal has passed 29 to 0 with a secondary vote for immediate removal without deprecation of 29 to 1. https://wiki.php.net/rfc/release-md5-deprecation I've pushed two commits to remove MD5 from www.php.net and qa.php.net, however it should be noted that I left a fair amount of md5 in web-php because very old releases have neither GPG signatures nor SHA256 checksums, and while MD5 is weak and broken, it's better than nothing. -Sara https://github.com/php/web-php/commit/7018747e6f57316591f138614cf311901f76e844 https://github.com/php/web-qa/commit/808942b865e355f16c727dc2050c4ec9ef832f9a
