Set subdomain gateway to different configuration than https://dweb.link

[demovoidgan]

In IPFS WebUi, Revision 1ff4971, under "Configuration", "Public Gateway", for "Subdomain Gateway". Any URL other than https://dweb.link cannot be set.
I think you can do the test yourself, it's very simple, go to https://ipfs.github.io/public-gateway-checker/ choose any possible URL, put it in. You will see that later if you go to "Explore", whenever you go to "View on Public Gateway" it always uses https://dweb.link.

PS: I have already tried to restart the application
