YSLS files not being detected by language server

[TheMartianLife]

What is the current behavior?

Unity generated a YSLS file which can be used to tell the language server about functions, commands, and static strings used to register things in C#. But VSCode doesn't know where to look for this file, so it doesn't get used and these still end up unrecognised in the editor.

What is the expected behavior?

The editor is able to find and interpret this file, whether or not it is in the default location for Unity, and whether or not there is more than one .ysls file. There should ideally be a way to set in the project where this file goes or should be looked for.
