GFWlist lacks *.google.com.sg

[yichengxia]

Describe the bug
Sites like https://books.google.com will be redirected to https://books.google.com.sg while using proxy from Singapore.
I thought it should be added to gfwlist, but they said the URL has existed and it your own rules lack it.
Like what I just opened in gfwlist/gfwlist#1547

To Reproduce

1. Using route with gfwlist mode
2. See error

Expected behavior
Sites like *.google.com.sg should be visited through proxy tunnel in gfwlist mode.
