XDCR filtering keys docs use round brackets instead of curly braces

For example:

(n) Matches n occurrences of the previous character or expression.

The parentheses should be updated to braces here.

We can create a test document with key aaaaa to test the XDCR filter. Using REGEXP_CONTAINS(META().id, 'a(5)'), as per the documentation, gives no match, whereas REGEXP_CONTAINS(META().id, 'a{5}') does match.
