fix(rust): remove rls and rust-analysis for Rust 1.87+ compatibility (#1362)

* fix(rust): remove rls and rust-analysis for Rust 1.87+ compatibility

Rust 1.87.0 and later have removed the long-deprecated RLS and rust-analysis
components. This change updates the install script to only add rust-src,
rustfmt, and clippy, preventing build errors during feature installation. See:
https://github.com/rust-lang/rust/pull/126856
https://blog.rust-lang.org/2022/07/01/RLS-deprecation/
https://github.com/rust-lang/rustup/blob/a92432fc8b6d5d4e56ebd08ca1c45b7b1294c1bd/doc/user-guide/src/concepts/components.md#previous-components

Fixes: https://github.com/devcontainers/features/issues/1361

* Drop support for older rust version that do not have rust-analyzer

* Add rust-analyzer as replacement for rls

* Update devcontainer-feature version number

* Add proposed version options

* test(rust): Bump pinned rust version to one incl rust-analyzer
