These endpoints should not be proxied to a generic Synapse worker
without other preparation (setting up stream writers, sending traffic
to a specific stream writer, etc.).

Disabling them for now. In the future, we'd like to fix up our awk
script to disable them automatically.

This is a fix up for 058fedff91

This prevented us from keeping our workers reverse-proxying definitions
updated since Synapse v1.54.0.

The last `workers.md` file we could parse is at commit
02632b3504.
Parsing regressed at commit c56bfb08bc071368db23f3b1c593724eb4f205f0,
because the introduction message for `synapse.app.generic_worker` said
"If":

> If a worker is set up to handle a..

.. which made the AWK script think that definitions below were
conditional (which they're not in this case).

This patch fixes up the regex for determining if a line is conditional
or not, so that it doesn't trip up. Hopefully, it doesn't miss something
important.

This reverts commit 986fe779cd.

The error was: error while evaluating conditional: 'matrix_synapse_s3_media_store_enabled' is undefined

This reverts commit a31017d716.

Added Storage Module to homeserver.yaml
