Merge rust-bitcoin/rust-bitcoin#858: Build the docs with test.sh

0d36455d74 Build the docs with test.sh (Tobin Harding)
8163497ab3 Use correct indentation (Tobin Harding)
3786680cc7 Use correct script name (Tobin Harding)

Pull request description:

  We currently build the docs as a separate CI job, we can however just do it as part of the `Tests` job using the nightly toolchain.

  Conditionally build the docs based on a `DO_DOCS` env var.

  Note, uses `--cfg docsrs` so can only be built run with nightly toolchain.

  - Patch 1: Fixes the incorrect file naming `ci.sh` -> `test.sh` in `CONTRIBUTING.md`.
  - Patch 2 - 4: Do trivial cleanup of `test.sh`.
  - Patch 5: Does the fix described above.

  Resolves: #850
