"Edit this page on Github" link is broken

For example when on the "Contributing" page, the link in the footer, directs to:

https://github.com/dudykr/oss-docs/blob/main/pages/docs/contributing.mdx

Instead of:

https://github.com/dudykr/oss-docs/blob/main/sites/stc/pages/docs/contributing.mdx

👋 I'm new to the project, and I'm considering submitting a PR for this, as well as make contributions to the stc repo itself.
