Missing PassengerTitle enum values

[Tom-Carpendale]

The docs specify 5 possible values for PassengerTitle, but the typescript types represent 3 of them in upper and lowercase, and miss the other 2:

duffel-api-javascript/src/types/shared.ts

Lines 67 to 70 in c308b4f

	/**
	* The passenger's title
	*/
	export type DuffelPassengerTitle = 'mr' | 'ms' | 'mrs' | 'MR' | 'MS' | 'MRS'
