docs: update readthedocs setup

[igaw]

Update the configuration so it works for two projects.

TODO:

• update readthedocs build service: use the correct yaml file.
• update the *readthedocs.yaml build instruction
• update github workflow

[Copilot]

Pull request overview

This PR updates the ReadTheDocs configuration to support separate documentation builds for two projects within the repository: nvme-cli and libnvme. The changes enable ReadTheDocs to build HTML documentation for nvme-cli (using asciidoc) and Sphinx-based documentation for libnvme (using RST) independently, likely as two separate ReadTheDocs projects.

Changes:

• Added support for building RST documentation separately via a new rst_docs build option
• Created separate ReadTheDocs configurations for nvme-cli (root) and libnvme (subdirectory)
• Removed GitHub Actions workflows for libnvme documentation and coverage, delegating documentation builds to ReadTheDocs

.github/workflows/libnvme-coverage.yml:1

• The libnvme-coverage.yml workflow file is being deleted. This workflow appears to run code coverage tests and upload results to Codecov, which is unrelated to documentation builds.

If this deletion is intentional as part of a broader cleanup or consolidation of CI workflows, please confirm. Otherwise, this might be an accidental deletion that removes code coverage reporting for the libnvme component.
