Documentation link and styling problems

[janvonneree]

Steps to reproduce

• open https://polyflow.info/

Expected behaviour

• [x] Button "technische Anforderungen" (beneath "Open Source Produkt") should open a documentation site

• [x] Button "technische Architektur" (beneath "Komponentenbibliothek") should open a documentation site

• [x] Styling of "CAMUNDA BPM Integration mit Camunda BPM" and "GENERISCH API für Intergration mit legacy Systemen" (beneath "Polyflow Integration") should be equal

• [x] open https://polyflow.info/news/ the news entry "Polyflow 3.3.0 veröffentlicht" shows a summary

• [x] the news entry "Polyflow 3.3.2 veröffentlicht" has the category "Neue Version"

• [ ] filtering news for "neue version" still shows the hero-sl-1.png

• [ ] open https://polyflow.info/impressum/ the link "hier widersprechen" should open a page

• [x] footer link "Dokumentation" should open a page

• [ ] footer copyright should be until 2024

Actual behaviour

• Button "technische Anforderungen" leads to a "page not found"

• Button "technische Architektur" leads to a "page not found"

• Background of "GENERISCH API ..." is bigger than "CAMUNDA BPM ..."

• the news entry "Polyflow 3.3.0 veröffentlicht" dose not show a summary

• the news entry "Polyflow 3.3.2 veröffentlicht" has the category "Unkategorisiert"

• filtering news for "neue version" dose not show hero-sl-1.png. Spacing looks a bit wered

• open https://polyflow.info/impressum/ the link "hier widersprechen" leads to a "page not found"

• footer link "Dokumentation" leads to a "page not found"

• footer copyright is until 2021
