Prepare release 5: BEdita API >= 5.36.0, php >= 8.3, node >= 20 + refactor clone

[didoda]

This introduces some breaking changes:

• php >= 8.3 (8.3.3 on scrutinizer analysis)
• bedita api >= 5.36.0
• cakephp >= 4.5
• node >= 20
• bedita/i18n >= 5
• bedita/webtools >= 5.0.1 (bedita/php-sdk >= 4)

and other changes (lib version update).

This uses BEditaClient->clone (with bedita/php-sdk:4): a refactor is applied and clone is done via a single API call.
