[src] links should point to the "Source" tab

[MHordecki]

Right now, [src] links in docs point at rustdoc-generated source listings such as this one. Given that docs.rs has its own native source tree browser, those links should point to that instead.

Don't do this until you have equivalent link-to-line functionality.

Triage: This can conceivably done with redirects, but we still don't have the same functionality as the source view generated by rustdoc

There is work ongoing on this at rust-lang/rust#69167, but it won't be done any time soon.

One issue with this may be that rustdoc creates pages for generated src too, check the [src] link on this page: https://docs.rs/web-sys/0.3.35/web_sys/console/fn.assert.html (but don't click it, it goes to a 90MB HTML file).
