Link to pyo3.rs/main from pyo3.rs/master?

[nw0]

We've renamed in #1130, but today I was reading the guide and accidentally used an old link to https://pyo3.rs/master rather than the up-to-date https://pyo3.rs/main. Perhaps we could add a prominent banner on the old master docs linking to the new ones, or even remove the old docs altogether?

Thanks for reporting. I think I can use a symlink to make the link transparent...

The docs on https://pyo3.rs/master now show the same content as https://pyo3.rs/main. Thanks again for the heads up.
