Runs Rust documentation tests.

Example:

Suppose you have the following directory structure for a Rust library crate:

```
[workspace]/
  WORKSPACE
  hello_lib/
      BUILD
      src/
          lib.rs
```

To run [documentation tests][doc-test] for the `hello_lib` crate, define a
`rust_doc_test` target that depends on the `hello_lib` `rust_library` target:

[doc-test]: https://doc.rust-lang.org/book/documentation.html#documentation-as-tests

```python
package(default_visibility = ["//visibility:public"])

load("@io_bazel_rules_rust//rust:rust.bzl", "rust_library", "rust_doc_test")

rust_library(
    name = "hello_lib",
    srcs = ["src/lib.rs"],
)

rust_doc_test(
    name = "hello_lib_doc_test",
    dep = ":hello_lib",
)
```

Running `bazel test //hello_lib:hello_lib_doc_test` will run all documentation tests for the `hello_lib` library crate.
