Update Dockerfile to install latest version of rust

the apt version of rust is 1.5, while the latest stable
version of rust is 1.79.
By using the older version of Rust, it is not possible to
compile cairo-lang-test-utils due to the following error:

```console
#13 193.7 error[E0658]: use of unstable library feature 'result_option_inspect'
#13 193.7   --> /root/.cargo/registry/src/index.crates.io-6f17d22bba15001f/cairo-lang-test-utils-2.7.0-rc.3/src/parse_test_file.rs:74:34
#13 193.7    |
#13 193.7 74 |         fs::File::open(filename).inspect_err(|_| log::error!("File not found: {filename:?}"))?;
```
