Build android standalone throws Joi error

[byCedric]

Description

When running expo build:android I'm running into a joi-related error.

It looks like Joi.strict() is deprecated, in favor of Joi.any().strict(). (see release notes for Joi 16). I see that we upgraded to 17, might be good to check if we have more of these issues in the code.

Expected Behavior

Joi shouldn't fail.

Observed Behavior
