Error in installation documetion for Release 3.4 (Elasticsearch installation)

[stefanCCS]

The current installation documentation
https://github.com/kitodo/kitodo-production/wiki/Installationsanleitung-f%C3%BCr-Kitodo.Production-3.4#2-softwarepakete-installieren
contains for ElasticSearch the following (among other commands):
sudo add-apt-repository "deb https://artifacts.elastic.co/packages/7.x/apt stable main"
Problem is, this will install the latest 7.x version (currently 7.15) but not the intended 7.10 version.
(which might be not a good idea, at least due to license conditions).

To install the (today available) latest 7.10.2 version the following procedure runs ok (Ubuntu):
(reference: https://www.elastic.co/guide/en/elasticsearch/reference/current/deb.html)

cd /tmp
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.10.2-amd64.deb
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.10.2-amd64.deb.sha512
shasum -a 512 -c elasticsearch-7.10.2-amd64.deb.sha512
sudo dpkg -i elasticsearch-7.10.2-amd64.deb
sudo systemctl enable elasticsearch
sudo systemctl start elasticsearch

To check installation you might do:

sudo systemctl status elasticsearch
curl -X GET "localhost:9200/?pretty"

@solth : This is still open and IMO should be added/changed for Release 3.5 installation documentation
(see also #4841 and #4842)
