Validation of postcodes in the United Kingdom prevents saving profile data

Description

Using Profile Store REST API, create new profile or update existing profile using POST/PUT actions.
Include zip code in profile data in profile.Info.ZipCode and use valid postcodes in the United Kingdom, for example:

• EC1A 1BB
• W1A 0AX
• M1 1AE
• CR2 6XH
• DN55 1PT
  etc

Expected: profile data is saved.

Observed: 400 Bad Request and error object with the message like
Invalid value.
Info.ZipCode: DN55 1PT

Note: some of postcodes are still accepted.
