Move Exception handling to General section

[ssarmokadam]

Validate if current exception handling document can be followed for Quarkus as well or any further changes required in it. If it is common for both move it to general section else add Exception Handling for devon4j and Quarkus in respective sections.

The documentation is not spring specific in any way:
https://github.com/devonfw/devon4j/blob/master/documentation/guide-exceptions.asciidoc

However, it is specific for the requirement of i18n and requires the usage of mmm-util-nls.
As we are changing towards less framework and minimized dependencies as well as opt-in rather than opt-out, we should instead consider to strip all these mmm dependencies and put a minimal exception base-class into our app template that has no external dependencies.
BTW: If someone wants to use such library, he should consider using io.github.m-m-m:mmm-base instead. It is improved and much more lightweight. Then you can add io.github.m-m-m:mmm-nls on top to add I18N/L10N.

I created #562 and hence close this issue.

This has always been the case:
