chore(test): bind mount read only in compose file for testing

[eitsupi]

#2286 (comment)

It is safer to do bind mounts with read only to prevent file permissions from being changed from the containers.

mysql container seems executing chown when start up.

Low priority question — but does this mean we can remove this file now?

[eitsupi]

We need to set secure-file-priv="" either in the configuration file or in the command.
Perhaps it is more concise to write the command in the compose file, so I changed it in #2359.
