Update Matrix Room Search indexing statistics

This brings the values up-to-date as of the latest indexing run done
today. Due to a bug, the previous values were somewhat off.
The new numbers are different and actually demonstrate that the situation is
much worse than initially imagined.

CHANGELOG.md

@@ -19,7 +19,7 @@ The **historical reasoning** behind this change is as follows:
 
 - In Synapse v1.7.0 (~2019), `allow_public_rooms_over_federation` [got disabled](https://github.com/matrix-org/synapse/blob/e9069c9f919685606506f04527332e83fbfa44d9/docs/upgrade.md?plain=1#L1877-L1891) by default in a [security-by-obscurity](https://en.wikipedia.org/wiki/Security_through_obscurity) workaround for misconfigured servers. See the [Avoiding unwelcome visitors on private Matrix servers](https://matrix.org/blog/2019/11/09/avoiding-unwelcome-visitors-on-private-matrix-servers/) `matrix.org` blog article. We believe that people wishing for a truly private server, should [disable federation](docs/configuring-playbook-federation.md#disabling-federation), instead of having a fully-federating server and trying to hide its public rooms. We also provide other workarounds below. We (and the Synapse team, obviously) believe that Matrix should federate by default, so federating the public room list seems to make sense.
 
-- [etke.cc](https://etke.cc/) has been developing the free-software [Matrix Rooms Search](https://gitlab.com/etke.cc/mrs) project for a while now. One public (demo) instance of it is hosted at [matrixrooms.info](https://matrixrooms.info/). This search engine tries to go through the Matrix federation and discover & index public rooms to allow people to find them. We believe it's vital for Matrix (and any chat or social network for that matter) to be more discoverable, so that people can find communities and others to talk to. On 19th of October 2023, `matrixrooms.info` was indexing `23831` Matrix servers. Of these, only `1937` servers (8%) were making their public rooms discoverable. Who knows what wonderful communities and rooms are available on these 92% other Matrix servers that are supposedly federating, but are still gate-keeping their public room list. Indubitably, many of these servers are hosted via matrix-docker-ansible-deploy, so we feel partially responsible for making Matrix federation less useful.
