docs: update CLI install command to pip install hydradb-cli

[Aadil-5122]

Summary

Update the HydraDB CLI plugin page to use the standard PyPI install command now that the package is published.

Changes

• plugins/cli.mdx: Changed install command from pip install git+https://github.com/usecortex/hydradb-cli.git to pip install hydradb-cli
• Removed the note about PyPI publishing being pending

Note: Merge this PR after hydradb-cli is published to PyPI (after usecortex/hydradb-cli#9 is merged and a release is created).

Testing

• Verified the MDX file renders valid Mintlify syntax
• No other files affected

Greptile Summary

This PR updates the HydraDB CLI install command from a git-based URL to pip install hydradb-cli and removes the note that PyPI publishing was pending.

• The PR description itself contains a blocking merge condition: "Merge this PR after hydradb-cli is published to PyPI (after chore: add PyPI publish workflow, update README with pip install and docs link hydradb-cli#9 is merged and a release is created)." A search for pypi.org/project/hydradb-cli found no results, suggesting the package is not yet live. Merging now will break the documented Quick Start for all users.

Confidence Score: 4/5

Do not merge until hydradb-cli is confirmed live on PyPI — the PR author's own note makes this a precondition.

The change itself is a single-line docs update with no logic errors. The P1 concern is purely a timing/precondition issue: the PR author explicitly flagged the package must be published first, and the package does not appear to be on PyPI yet. Once the PyPI release is confirmed, this is a 5/5 merge.

Important Files Changed

Filename	Overview
plugins/cli.mdx	Switches install command from git URL to pip install hydradb-cli and removes the "PyPI pending" note — but the PR description explicitly states this should only be merged after the package is published to PyPI, which cannot currently be confirmed.
