Handling of web versions

[CodeDoctorDE]

Hello,

Currently we have 4 versions of the app:

• Stable (Will be published as a release on github and on the stores)
• Nightly (Will be published as prerelease on github and in the beta programs of the stores)
• Main (The stable branch on github where all hotfixes of the app will be published + the main web version https://web.butterfly.linwood.dev)
• Preview (The develop branch on github where all the work is happening + the preview web version https://preview.butterfly.linwood.dev)

The last 2 are rolling releases and will be changed if there are new commits. This means, that they aren't the same as the version installed.
