When trying to use OTP28.0-rc1, Elixir fails to compile these modules
because a module attribute cannot be a regex. It is not yet clear
whether it's something to be fixed in Elixir for OTP28 compatibility
or something that accidentally worked in the past, but either way,
using a string as an attribute is equally good and works all OTP
versions, including OTP28.0-rc1.

This is not sufficient to build RabbitMQ on OTP 28.0-rc1 but it fixes the first problem that we hit. It might be that Elixir will support regex module attributes once it supports OTP 28, but we don't have to wait - this minor refactor just makes our code compatible with OTP28 without changing anything of substance.
