fix: replace logger

[vitormattos]

The previous logger approach was removed at Nextcloud 30 and was needed to be replaced by Psr\Log\LoggerInterface

This PR fix:

Error: Call to undefined method OC\Server::getLogger() in /var/www/html/apps-writable/cms_pico/lib/Migration/Version010000From000908.php:65

Thank you for your contribution! ❤️

First of all, please note that cms_pico is abandoned dev-wise, thus there isn't going to be a new release in the foreseeable future. There's currently no stable version of cms_pico supporting any of Nextcloud's still officially supported branches; people still using cms_pico do so at their own risk and use custom app builds (usually) based on the cms_pico-1.0 branch.

You can ignore the failing CI, just wanted to see whether it's more broken than last time I checked - it indeed is.

If you're willing to invest more time nevertheless, can you please rebase on the cms_pico-1.0 branch? The master branch is the dev version of cms_pico v2.0. Just switching the PR's base unfortunately doesn't work properly. Did you check all usages of $logger to be compatible with the new LoggerInterface? Unfortunately I don't have the time to do a proper review of your PR, but the changes look good; so, if you affirm that you did check all usages, I'll merge your PR nevertheless. Thanks again!
