Move ACA CLI installers to aca-cli/preview for public preview (#1739)

* Move ACA CLI installers to aca-cli/preview for public preview

- Move install.sh, install.ps1, latest-version.txt from docs/early/aca-cli to aca-cli/preview; repoint latest-version.txt URL and pin version to aca-cli-v0.1.0-preview.

- Add a quick aca-cli/preview/README.md (install, uninstall, supported platforms, link to the preview release).

- Delete docs/early/aca-cli and docs/early/python-sdk.

- Remove dangling docs/early/python-sdk references from plugin/skills/aca-sandboxes/SKILL.md.
