Add pre-release check when releasing extension
There should be some checks for basic things when there is an extension release (via form, SOAP or REST)
composer.jsonfile (?) and mandatory fields inside
- Link to the repository (?)
autoloadinformation if Classes folder exists (?)
- Documentation exists in any way (Readme file, Documentation folder including not only fake)
Additionally provide this as GitHub Action, GitLab job, etc. for automatic checks before even tags are set.
