joi.alternatives error message too generic

[maxuai]

• node version - 18.12.1
• celebrate version - 15.0.1
• joi version (via npm ls --depth=0 | grep joi) - 17.2.3

My joi schema looks like this:

`{

    param: Joi.alternatives().try(Joi.object({
      name: Joi.string(),
    }), Joi.object({
      name: Joi.number(),
    })),
}`

Here is an example value that is not working as expected:

(param: { name: true })

The issue I am having with celebrate is:

When using joi.alternatives with objects and none of the alternatives matches the error message is too generic like "message": "\\"param\\" does not match any of the allowed types". What would be needed is to add the context from the the error details to the validation object in the error response.

I would have a branch with a fix ready, but am am not allowed to push ;)
