Increment recommended php version
PHP has just EOLed php 7.3 https://www.php.net/eol.php
We are just about to release the 5.45 ESR and we could take the opportunity to drop support for older php & mysql ie drop support for php 7.2 & mysql 5.6
The gut check in informal discussion was to leave that for the next ESR and instead just increase our recommended versions.
While we support php 8.0 if has pretty low usage at the moment - so 7.4 seemed like the right pick
