[Bug]: Server doesn't handle periods in path parameters

[roberttod]

What's not working?

This is linked to #9714 which fixes this issue for query parameters.

As discussed with @dthyresson , the Redwood dev server returns 404s when there is a . in a path parameter. E.g. the url http://localhost:8910/somepath/1.2/view would 404 even with a matching route. If you navigate to the route on the client, there is no error but reloading will make a request to the server.

This is not the case for production for a) a standard Netlify deployment or b) the recommended Heroku deployment with nginx. Instead, the static file server will always return index.html if there are no assets found to match the uri.

There are a few workarounds for this

1. Let dev fail when you reload, and test by navigating to the URL you are working on
2. Replace . with another character when writing and reading the url
3. Put the . in a query parameter, which means you loose typing (and the URL is very long in my case)

It should be fairly simple and safe (noting the existing production functionality) to fix this by returning index.html instead of a 404.

How do we reproduce the bug?

Make any path with a String parameter in the router, and load a url with a . somewhere in the paramater.

What's your environment? (If it applies)

No response
