Add option to turn off noisy initialization welcome message

[Eric-Arellano]

Meilisearch outputs about 25 lines when starting up the process, including Ascii art. In our production environment, this output results in each distinct line being a distinct log entry because of how the observability is configured. This makes our logs much noisier.

The option --log-level makes no impact because it does not impact the welcome message.

I propose adding --no-welcome-message to turn off the welcome message entirely. No changes to the default behavior. This option name mirrors --no-analytics.

If you are open to this idea, I'm happy to submit a PR.

Hi @Eric-Arellano , would you consider instructing your logging system to filter lines starting with FATAL, ERROR, WARN, INFO, DEBUG and TRACE?
