Fix edit button on Read the Docs with stable branch builds

[pradyunsg]

What's happening?

The current logic for computing the GitHub URLs in Furo, when on RTD is:

https://github.com/pradyunsg/furo/blob/490527b2aef00b1198770c3389a1979911ee1fcb/src/furo/theme/furo/components/edit-this-page.html#L24

This differs from sphinx-rtd-theme (https://github.com/readthedocs/sphinx_rtd_theme/blob/9899ee4ee2f547f81e51297dc12317f018e62fdd/sphinx_rtd_theme/breadcrumbs.html#L39) and should be fixed to align with that.

Reproducer

1. Build Sphinx documentation set on RTD, with a stable branch or tag.
2. See the edit page button's URL -- it has the commit hash rather than the source ref.

Expectation

The generated URL should point to the source ref.

Is there anything blocking changing this? Is it as simple as updating the path you linked:

diff --git a/src/furo/theme/furo/components/edit-this-page.html b/src/furo/theme/furo/components/edit-this-page.html

That is not gonna work since blob links are not what we wanna link to and those pages also don’t have an edit button. What we need to change to is linked inOP. It’s a matter of someone investigating and making the relevant changes.
