Add script to test release

[Neylix]

Description

To make it easier to test the release and hot reload, I created a script that allow to test it in dev mode.
Also change the DB folder (mut_dir) in dev mode so the data is not impacted by mix clean and the folder remain the same while testing release

I realize that I didn't tested the data folder while running in docker

This is not related to this PR but I get an error when starting the release because of a missing configuration:

** (ArgumentError) could not fetch application environment :tx_cache_bytes for application :archethic_web because the application was not loaded nor configured

indeed the config is not in the test_release/var/sys.config. It is in the config.exs though.
This is because ArchethicWeb is not an application.
I think we should move these configs into config :archethic, ArchethicWeb.API.WebHostingController

Proposition:

I managed to hot reload a release with this tool. Works fine, but there's a minor grep warning:
