Cmake 0.9.0 Documentation Page Contains Stale Refrence to Version 0.1.0

This [documentation page](https://bazelbuild.github.io/rules_foreign_cc/0.9.0/cmake.html) for version 0.9.0 contains a stale reference to version 0.1.0 of the library:
```
http_archive(
name = "rules_foreign_cc",
sha256 = "c2cdcf55ffaf49366725639e45dedd449b8c3fe22b54e31625eb80ce3a240f1e",
strip_prefix = "rules_foreign_cc-0.1.0",
url = "https://github.com/bazelbuild/rules_foreign_cc/archive/0.1.0.zip",
)
```

The stale reference is [here](https://github.com/bazelbuild/rules_foreign_cc/blob/b7074f111e835a2e4c817220f843669ff969d24c/foreign_cc/cmake.bzl#L26) in the code.
This could be modified to point to the main index page (which is up to date).

Open foreign_cc/cmake.bzl at the referenced line and inspect how the CMake documentation page is assembled. Replace the stale version 0.1.0 reference with a link to the up-to-date main index page, then verify that the 0.9.0 documentation no longer points to the old library version.
