Don't go to the ext host for default terminal shell/args in tasks #123732
Description
I noticed this call here which goes to the exthost:
It seems to be the only usage of that proxy call, you can now call this on the renderer for the same thing:
ITerminalProfileResolverService.getDefaultProfile({
os: terminalBackendOS, // probably remoteAgentService.getEnvironment().os || OS
remoteAuthority: terminalBackendRemoteAuthority,
allowAutomationShell: true
});
