Pick up dashes in dynamic parameter names

[brophdawg11]

Fix bug where dashes were not picked up as part of the dynamic parameter name:

// A URL `/whatever` should match with `useParams()["foo-bar"] === "whatever"`
let routes = { path: ":foo-bar" };

Without this, the portion after the dash was being incorrectly scored/counted as a static segment, and we only support dynamic parameters as the full URL (#9506)

Closes #11159
