Bug 1744324 [wpt PR 31882] - URLPattern: Emit `{}` around custom names followed by a regexp group., a=testonly

Automatic update from web-platform-tests
URLPattern: Emit `{}` around custom names followed by a regexp group. (#31882)

This CL fixes another problem case from:

https://github.com/WICG/urlpattern/issues/145

In this case we need to preserve `{ ... }` braces around a named group
followed by a group that may be emitted in regexp `( ... )` group.  We
don't want `{:foo}(.*)` to be changed to `:foo(.*)` since that changes
the meaning from two groups to a single group.
