### Steps to reproduce

1. Enable `Enforce Windows compatibility` in Nextcloud (https://nextcloud.example.com/index.php/settings/admin)

2. Create a Project with the following name `Test: Nextcloud1`

3. Enable Nextcloud storage in the project with automatic managed folders

<br>


### What is the buggy behavior?

* OpenProject try to create a folder that includes the `:` character

* The colon is not allowed on Windows systems


### What is the expected behavior?

1. If Nextcloud enforces windows compatibility, the invalid characters need to be replaced

2. The folder gets created in Nextcloud
