PHP 8.3 and other updates

• Upgraded to php 8.3
• Added adminer as alternate database explorer tool
• Added instructions on how to upgrade to a new version of rdc by copying over your old database and www folders.
• Added instructions for localhost SSL configuration (so https://redcap.local or https://localhost works without errors)
• Cleaned up vscode XDEBUG setup so it should virtually 'work out of the box' with a few minor steps (in documentation)
• Switched out mailhog and replaced it with mailpit - a more modern and supported email aggregator for localhost
• Updated log rotation for log files so that your local /logs directory shouldn't get out of control.
