Was just browsing the docs, an saw that the variable names are prefixed with camunda. not operaton..

This is also technically incorrect.

I did a quick search and found the following entries, where I suppose we should change it too (includes broken links):

documentation/docs/get-started/spring-boot/configuration.md

Line 23 in f5356f8

camunda.bpm:

documentation/docs/documentation/introduction/extensions.md

Line 29 in f5356f8

You can also learn about [contributing code to the core Operaton codebase](https://camunda.com/developers/how-to-contribute/).

documentation/docs/documentation/installation/full/wildfly/manual.md

Line 23 in f5356f8

* For WildFly ≥27 / JBoss EAP 8, download the [Operaton WildFly distribution](https://downloads.camunda.cloud/release/operaton-bpm/wildfly/).

(and line 24, 154-156, 168/169)

documentation/docs/documentation/installation/full/tomcat/pre-packaged.md

Line 12 in f5356f8

1. Download the pre-packaged distribution from https://downloads.camunda.cloud/release/operaton-bpm/tomcat/.
