11ty peeps, say I have the following:

pages/
– 10-my-first-page.md
– 20-my-second-page.md
– 30-my-third-page.md

I'm setting the permalink thusly:

permalink: "{{ page.filePathStem }}/"

What is the easiest way to get 11ty to ignore the number in the slug that I am using just for sorting purposes? I would like the permalink to be, for example:

/pages/my-first-page/index.html

But currently I get:

/pages/10-my-first-page/index.html
