This werk introduces a fix to the pattern attribute in various rest-api schemas.

To avoid partial matches, regex patterns should start with the caret and end with the dollar symbol.

Also, the + symbol should be preferred over the * symbol as the * symbol allowed for zero or more matches instead of 1 or more which is what the + symbol gives us.

For patterns that list possible options, e.g. monday|tuesday|wedneday... etc they have instead been removed and replaced with enums.
