Trying to update a test wiki running 1.34.2 and executing maintenance/update.php, I get
`wikimedia/parsoid: 0.12.0-a22 installed, 0.12.0-a23 required.
Error: your composer.lock file is not up to date. Run "composer update --no-dev" to install newer dependencies
can't execute update script on wiki-t05.hrz.uni-bielefeld.de: Interrupted system call`
It is unclear to me what I should do, I don't see a script/executable "composer". And it would be great if the installer could handle this on it's own.
