Rename camunda/zeebe repo

[Zelldon]

Description

The repository camunda/zeebe will be renamed to camunda/camunda, this PR adjusts all references to this repository.

WHY The name of this repository will be changed to align better with its new role as a monorepo containing multiple products of the stack. https://github.com/camunda/zeebe/issues/18206

Details

I renamed all occurrences of github.com/camunda/zeebe. I didn't do this for camunda/zeebe as this will change occurrences for docker images (which we do not plan to change yet).

For posterity, the following script has been used.

#!/bin/bash

set -euox pipefail
path=$1

# Replace occurence in markdown files
find "$path" -type f -exec sed -i -E 's|github.com/camunda/zeebe([/#])?|github.com/camunda/camunda\1|g' {} \;

count=$(git -C "$path" status | grep modified -c)
echo "$count files have been updated."

if ag 'github.com/camunda/zeebe/' "$path" > /dev/null
then
  echo "There are still some occurences left, that need to be renamed! "
else
  echo "All occurences of 'github.com/camunda/zeebe/' have been renamed!"
fi
