Add support for JetBrains server in openFile

[IliyaBrook]

The code has been updated to include an additional case for 'JetBrains_server' in the switch statement. This allows the openFile function to generate a URL for opening files on a JetBrains server, respecting the particular file path and line.

The changes:

case 'jetbrains_server':
  url = `http://localhost:63342/api/file/?file=${filePath}&line=${line}`;
  break;
