bugfix: route interception with dynamic paths (#51526)
### What?
Paths with interception markers adjacent to dynamic segments are not correctly parsed, which leads to the path match logic failing.
### Why?
`getParametrizedRoutes` checks for brackets but isn't expecting to receive an interception marker. For example, a path of `/photos/(.)[author]/[id]` results in the following regex:
`/^\/photos\/\(\.\)\[author\]\/([^/]+?)(?:\/)?$/`
This will not match a path of `/photos/(.)zack/1` since it retained the `[author]` brackets.
`getSegmentParam` has a similar issue when getting values for path params, though we can just skip the interception markers and go straight to the params.
