Subject: [PATCH] fix(esphome): Update persistence for correct cache
 directories (#32763)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

**Description**
I figured this out when looking for why my volsync backup was so large
for what should be just a couple yaml files. This saves me 1.3GB of S3
storage, but that quantity will vary.

Now we're mounting the cache directories that esphome is expecting. If
they don't see these directories existing, then they change the location
to be inside the config directory so that these things are cached.

It looks like we used to have this working, but upstream probably
changed the directories at some point. They don't seem to have clear
documentation that I could find. I found these directories [in their
github](https://github.com/esphome/esphome/blob/dev/docker/docker_entrypoint.sh).
