Some links in README.md are not found

The following links docker buildx install and docker buildx uninstall in README.md are not found.

Running the command docker buildx install sets up docker builder command as an alias to docker buildx build. This results in the ability to have docker build use the current buildx builder.

To remove this alias, run docker buildx uninstall.

I think this relates to a change in docs generation where hidden commands don't generate documentation anymore, which makes sense imo:

• buildx/commands/install.go

  Line 50 in 695200c

  Hidden: true,

• buildx/commands/uninstall.go

  Line 56 in 695200c

  Hidden: true,

@dvdksn I wonder if we could just remove this section from the README: https://github.com/docker/buildx?tab=readme-ov-file#set-buildx-as-the-default-builder and add it to https://docs.docker.com/build/concepts/overview/#buildx instead without links to cli ref?

@crazy-max yeah we can do that. I could also clarify the discrepancy between a vanilla docker build and a docker buildx build w.r.t. default builder.

Ah true we should explain this. I see this content that is almost correct: https://docs.docker.com/build/concepts/overview/#buildx

Buildx and BuildKit are both installed with Docker Desktop and Docker Engine out-of-the-box. When you invoke the docker build command, you're using Buildx to run a build using the default BuildKit bundled with Docker.

We could add here how builder selection works when docker build is invoked vs docker buildx build.
