Adding an option to surpress or modify the non-existent root directory warning

Prerequisites

• I have written a descriptive issue title
• I have searched existing issues to ensure the feature has not already been requested

🚀 Feature Proposal

Hey, would it be possible to surpress or modify (preferably) the warning that gets logged, when one of the root directories from the config does not exist, such as:

"root" path "..." must exist

I want to set my own message when this occurs. Would it make sense? If so, I can create a PR for this feature.

Motivation

No response

Example

I am imagining something in the lines of:

fastify.register(fastifyStatic, {
  root: './static',
  getPathNotFoundWarning: (path) => `"root" path "${path}" must exist`,
});
