Update CONTRIBUTING.md to use RustRover instead of IntelliJ Rust

JetBrains has transitioned from the IntelliJ Rust plugin to RustRover
as their dedicated Rust IDE. This updates the documentation to reflect
this change while maintaining backward compatibility with the existing
cargo dev setup intellij command.

Changes:
- Replace IntelliJ Rust references with RustRover in CONTRIBUTING.md
- Update links to point to official RustRover homepage
- Update development guide in book/src/development/basics.md
- Keep existing command names for backward compatibility

 ## Getting code-completion for rustc internals to work
 
-### IntelliJ Rust
-Unfortunately, [`IntelliJ Rust`][IntelliJ_rust_homepage] does not (yet?) understand how Clippy uses compiler-internals
+### RustRover
+Unfortunately, [`RustRover`][RustRover_homepage] does not (yet?) understand how Clippy uses compiler-internals
 using `extern crate` and it also needs to be able to read the source files of the rustc-compiler which are not
 available via a `rustup` component at the time of writing.
 To work around this, you need to have a copy of the [rustc-repo][rustc_repo] available which can be obtained via
 `git clone https://github.com/rust-lang/rust/`.
 Then you can run a `cargo dev` command to automatically make Clippy use the rustc-repo via path-dependencies
-which `IntelliJ Rust` will be able to understand.
+which `RustRover` will be able to understand.
 Run `cargo dev setup intellij --repo-path <repo-path>` where `<repo-path>` is a path to the rustc repo
 you just cloned.
 The command will add path-dependencies pointing towards rustc-crates inside the rustc repo to
-Clippy's `Cargo.toml`s and should allow `IntelliJ Rust` to understand most of the types that Clippy uses.

 Just make sure to remove the dependencies again before finally making a pull request!
