fix: #4316 .

Apologies for the lack of clarity on this issue. I aim to build and publish the API documentation for object-store-opendal using rustdoc, similar to what we've done with opendal:

opendal/.github/workflows/docs.yml

Lines 37 to 72 in 2665e63

	build-rust-doc:
	runs-on: ubuntu-latest
	steps:
	- uses: actions/checkout@v4
	- name: Setup Rust toolchain
	uses: ./.github/actions/setup
	with:
	need-rocksdb: true
	need-protoc: true
	github-token: ${{ secrets.GITHUB_TOKEN }}
	# Revert to nightly after https://github.com/apache/opendal/issues/4161 addressed
	- name: Setup Rust Nightly
	run: |
	rustup toolchain install nightly-2024-01-01
	- uses: actions/setup-java@v4
	with:
	distribution: temurin
	java-version: '17'
	- name: Build OpenDAL doc
	working-directory: core
	run: cargo +nightly-2024-01-01 doc --lib --no-deps --all-features
	env:
	LD_LIBRARY_PATH: ${{ env.JAVA_HOME }}/lib/server:${{ env.LD_LIBRARY_PATH }}
	# Enable cfg docs to make sure docs are built.
	RUSTDOCFLAGS: "--cfg docs"
	- name: Upload docs
	uses: actions/upload-artifact@v3
	with:
	name: rust-docs
	path: ./core/target/doc

So we can read object-store-opendal docs like https://opendal.apache.org/docs/rust/opendal/

Got this, I had a misunderstanding here before.

There's a typo here, I've submitted a PR to fix it.

object_store_opendal document has been uploaded in https://opendal.apache.org/docs/object-store-opendal/object_store_opendal/ but does not point to it correctly.
