Run in Neo4j Browser gives out no notice when Neo4j Desktop is not installed

[stefano-ottolenghi]

The run buttons only have an effect if Neo4j Desktop is installed, as they go through the neo4j-desktop:// protocol. Not everybody has it, and as it currently stands it's impossible to know that that's a prerequisite. We should alert users when clicking, if the protocol is unavailable.

I don't think you can detect whether the software is installed. We could instead update these links to point to browser.neo4j.io?cmd=edit&arg=url%20encoded%20cypher%20statement instead

It looks like you are right: you can't inquire whether a protocol has a handler registered in the browser, I guess for privacy reasons. I just assumed you could.

We could instead update these links to point to browser.neo4j.io

Unless we can also automatically spin up an instance for them, so that the link actually runs the query, I don't think it would help much. You land there and it's not at all easy to understand that you first need to get a running instance, connect to it (with another query), and then come back to the button.

As an alternative, I feel like the best we could do is put a clarifying note on hover?

#146 removed the button altogether.
