Let rust-analyzer ship on stable, non-preview

The consensus on rust-lang/rust-analyzer#12432 seems to be that we are ready for `rust-analyzer` to ship as a rustup component on the beta and stable channels. This won't always be the preferred distribution method, e.g. the VS Code extension will probably still independently update to its weekly releases, but it's still useful to have a component that follows the release train with the rest of the Rust toolchain. So this removes the nightly-only gating on the bundled component, and removes the "-preview" suffix as well by the usual renaming mechanism.
