fix(readme): tls docs path

[galesky]

The link to the --link docs that relate to TLS is broken (404) as it is pointing to a previous release version whose docs are not available.
This PR updates the docs URL.

I've also run a search on the project to make sure no other links using that version where there and I haven't found any.

As an extra, I'd suggest using the latest path rather than a specific version

p.s. I've skipped creating an issue as per docs:
Please create a GitHub Issue that includes context for issues that you see. You can skip this if the proposed fix is minor.

Thanks for catching this. And yes, a latest version path would be a great addition in the near future.
