Routes that end with .html

[tszyan]

Shouldn't routes that end with .html be possible using the following route path:

path: '/category/:alias.html'

or perhaps with some brackets around alias?

In the documentation, we have the :withHtmlExtension example here:
https://docs.solidjs.com/solid-router/concepts/path-parameters#validating-parameters
but in the end, we can't get the parameter without '.html' in its value.

Usually, we need only 'category_alias' as the value when matching '/category/category_alias.html'.
Upon reviewing the @solidjs/router code, it seems that this change can be implemented with minor adjustments to the createMatcher function.

Or is it possible to achieve this without these changes?
