Elasticsearch Admin version dropdown needs clarification

[dobooth]

In the Magento admin, you can choose your Elasticsearch version.
https://devdocs.magento.com/guides/v2.3/config-guide/elasticsearch/es-config-nginx.html#configure-elasticsearch-within-magento
In the dropdown, you have a value like "6.0+".
This is not clear enough. It is supposed to mean "all of v6" but it actually means "all versions 6 and higher".
Now that Elasticsearch is up to version 7, users are not sure whether we support v7, which we do not as of yet.
I suggest that we change the dropdown version numbers to a "6.x" format.
Also, ES v5 is EOL and should be removed, since PCI forbids EOL software.
It is unclear what the generic "Elasticsearch" option is for.

Hi @dobooth, isn't that already fixed by magento/magento2@cf1b084#diff-b2e0d454e4ffd542fa96dc1b7dc225d9 ?

Yes, it stems from magento/magento2#25674
