scripts: generate_rust_analyzer: quote: treat `core` and `std` as dependencies

Fix the `generate_rust_analyzer.py` script to ensure that the
`rust-project.json` it produces includes `core` and `std` in the `deps`
field for the `quote` crate.

`quote` directly references items from both `core` and `std`, so
rust-analyzer should treat them as dependencies to provide correct IDE
support.

For example, the `::quote::ToTokens` trait is implemented for
`std::ffi::CString`. With `std` listed in the `deps` field,
rust-analyzer can show the expected autocomplete for the
`::quote::ToTokens` methods on `std::ffi::CString`.

Verified the explicit uses of `core` and `std` using:

    grep -rnE 'core::|std::' rust/quote/
