Which Umbraco version are you using? (Please write the exact version, example: 10.1.0)

15.0.0

Bug summary

In file Umbraco.Cms.Core.Routing.ContentFinderByUrlAndTemplate, the base class is Umbraco.Cms.Core.Routing.ContentFinderByUrl and inside, the content finder is using FileService to locate the template. This results in not finding the actual node, and the content finder is not working as advertised (i.e. /foo/bar/template does not show content from /foo/bar using template "template").

Specifics

ContentFinderByUrlAndTemplate inherits from ContentFinderByUrl. It should be inheriting from ContentFinderByUrlNew.

I don't know how to make the pull request, I have a local working copy where I've done the changes required.

Steps to reproduce

1. Add ContentFinderByUrlAndTemplate to the list of content finders (see relevant documentation on how to do that)
2. Make sure that Umbraco is configured to accept alternate templates (see documentation for this)
3. Create a document type (e.g. "documentTypeTest")
4. Add two textstring fields, "stringA" and "stringB".
5. Create two templates (e.g. "templateA" and "templateB")
6. In "templateA" write code to display value of "stringA".
7. In "templateB" write code to display value of "stringB"
8. Assign both templates to document type
9. Set "templateA" to be default.
10. Create a node using documentTypeTest as doctype
11. Navigate to /path/to/node/templateB

Expected result / actual result

Expected: You should see a page with the value of stringB field.
Actual: 404 page.
