[3.19] community/rust-analyzer: upgrade to 2023.12.11

The proc-macro server in rust now uses API version 3 but rust-analyzer versions prior to 2023.12.11 use the old API version 2, resulting in an error when trying to build macros:

Failed to run proc-macro server from path /usr/libexec/rust-analyzer-proc-macro-srv, error: Custom { kind: Other, error: "proc-macro server's api version (3) is newer than rust-analyzer's (2)" }
