feat(iam): implement deleteTeam method

[designcode]

Note

Medium Risk
Destructive IAM team deletion is a sensitive operation; the change is small and follows existing team API patterns but callers can permanently remove teams if misused.

Overview
Adds deleteTeam to @tigrisdata/iam, completing team lifecycle support alongside existing create/edit/list helpers.

The new API issues a DELETE to teams/{teamId}, mirrors other team methods for client setup and status: 'error' handling, and returns { data: { teamId } } on success. Types and the function are re-exported from the package entrypoint. A minor changeset documents the release; Biome’s JSON schema URL is bumped to 2.5.8.

Greptile Summary

Adds the public deleteTeam IAM API and its release changeset, while updating the Biome schema reference.

• Exports new delete-team option and response types from the IAM package entrypoint.
• Sends a DELETE request for a supplied team ID and returns that ID on success.
• Adds a minor-version changeset for @tigrisdata/iam.

Confidence Score: 3/5

The PR is not safe to merge until deleteTeam uses the management endpoint and propagates application-level deletion errors.

The new operation currently targets the default IAM backend rather than the team management backend, and it can return success for response bodies that explicitly report an error.
