bug#50766: Regexp paren pairs in query-replace-regexp prompt should be highlighted

[ndame]

Emacs highlights parents by default, e.g. when point is after the closing
paren  the opening parent is highlighted.

If I type capturing parens in the query replace regexp prompt then the
paren pairs are not highlighted:

   Query replace regexp: \(something\)

They should be, so when typing a complex regexp with multiple capturing
parens then it's easier to see the pairs.
