fix(v9/nuxt): Do not drop parametrized routes (#17357)

[s1gr1d]

I just found out Nuxt is dropping spans for catch-all routes.

related to #16843 (as we have parametrized routes since then)

backport of #17357

Ah I see, this is because .*)* in routes would test positive for path.extname? I wonder if we can make the file name check more robust instead. Not sure if the regex works well enough. Like for example check that it only contains alphanumeric values? Not sure if this is any better though, so happy to go with this as well for now.

Yes exactly! theoretically, it would be also possible to put the regex just on the extname but I am not sure if this actually makes it more robust 🤔 There is only a limited set of how a parametrized route in Nuxt can look like.
