https://adobe.github.com/ is not a GitHub page any more; documentation should in stead mention https://adobe.github.io/

### Expected Behaviour

https://adobe.github.com/ to be alive as a GitHub page.

### Actual Behaviour

https://adobe.github.com/ is not a GitHub page any more

### Reproduce Scenario (including but not limited to)

Browse to https://adobe.github.com/

#### Steps to Reproduce

None (see archived page below under "logs")

#### Platform and Version

Latest Chrome x64 on latest Windows 10 x64.

#### Sample Code that illustrates the problem

None (see archived page below under "logs")

#### Logs taken while reproducing problem

See archived page: https://archive.is/6n7Uf

### Cause

https://adobe.github.com/ used to 302-redirect to https://adobe.github.io until 2019 (see https://web.archive.org/web/20190607103804/https://adobe.github.com/)

### Proposed change

Change all documentation from pointing to https://adobe.github.com/ or URLs under to the same URL but on the https://adobe.github.io/ subdomain.

At least the toplevel [README.md](https://raw.githubusercontent.com/adobe/adobe.github.com/master/README.md) still points to https://adobe.github.com in two places and should be changed. I have not checked other source files.

Beginne mit README.md, das laut Issue zwei veraltete Links zu adobe.github.com enthält, und durchsuche anschließend das Repository nach dieser Domain und allen darunterliegenden URLs. Aktualisiere die Dokumentationsverweise auf die entsprechenden adobe.github.io-URLs und überprüfe, dass keine alten Dokumentationslinks verbleiben.
