Twenty Nineteen: Remove the incorrect "flexible-header" tag.

This changeset removes the "flexible-header" tag from Twenty Nineteen, since the requirements for using this tag is that the theme includes support for a custom header with the flex-height and/or flex-width parameters, and Twenty Nineteen does not have support for header image.

Props poena, mukesh27, laurelfulford, audrasjb.
Fixes #46213.
