	// NewConfiguredProvider starts a _configured_ instance of the given
	// provider using the given configuration value.
	//
	// The evaluation system itself makes no use of configured providers, but
	// higher-level processes wrapping it (e.g. the plan and apply engines)
	// need to use configured providers for actions related to resources, etc,
	// and so this is for their benefit to help ensure that they are definitely
	// creating a configured instance of the same provider that other methods
	// would be using to return schema information and validation results.
	//
	// It's the caller's responsibility to ensure that the given configuration
	// value is valid according to the provider's schema and validation rules.
	// That's usually achieved by taking a value provided by the evaluation
	// system, which would then have already been processed using the results
	// from [Providers.ProviderConfigSchema] and
	// [Providers.ValidateProviderConfig]. If the returned diagnostics contains
	// errors then the [providers.Configured] result is invalid and must not be
	// used.
