room_directory replace matrix.org by matrixrooms.info

[Gredin67]

Problem

Look for existing public room:

• By default local server room directory shows up
• then matrix.org is suggested which hides the federation

Solution

• replace matrix.org by matrixrooms.info as room_directory

UX could be further improved by selecting matrixrooms.info rather than default local server public directory.
I guess this is a synapse config though @Josue-T ?

[Josue-T]

Thanks for your PR, interesting question. I didn't known the existence of matrixrooms.info which seem interesting.

Well, I dis some research and I didn't find any info about a config in synapse for this. And on other side it seem that in element Android for now it's matrix.org and as the user we can add a server. So I have more the feeling that this list is just handled fron client side. To me ideally we need to keep the official list which only contains matrix.org (for now) even if this is not ideals. And maybe we could provide a in the config panel a way to have to add a custom server and mention that this server provide a better list

My idea is also that we need to keep consistent with the official version, but provide a way to customize some parameters for user which would like to change it.
