Update remaining references to "graphql" program to be SolarThing Server

solarthing/web/README.md

Line 3 in fccc7eb

This module is used for the web application bundled with the `graphql` program.

GraphQl is not a program. Please look that up properly.

SolarThing Server used to be called "SolarThing GraphQL". Within older documentation that has not been updated in a while, it is referred to as the graphql program. The native install tabs on the SolarThing Server Setup refer to /opt/solarthing/program/graphql as the place to configure the problem.

Because the native install is deprecated, and because /opt/solarthing/program/graphql has special meaning, I will not be making the breaking change of renaming that directly.

However, you bring up a good point. The spot you found in the documentation could be improved to refer to SolarThing Server.
