Support Azure CLI v2.69.0+ managed identity authentication parameter change

[Copilot]

Azure CLI v2.69.0 replaced --username with --client-id for user-assigned managed identity authentication (azure-cli#30525). Without version-aware parameter selection, the action breaks on newer CLI versions.

Changes

• Version detection: Parse Azure CLI version on initialization, extract minor version number with fallback handling
• Conditional parameter selection in loginWithUserAssignedIdentity():
  • CLI < 2.69.0 → --username
  • CLI ≥ 2.69.0 → --client-id
• Test coverage: Version boundary tests (2.68.0, 2.69.0, 2.70.0), parse failure scenarios, edge cases

Implementation

async loginWithUserAssignedIdentity(args: string[]) {
    let azcliMinorVersion = 0;
    try {
        azcliMinorVersion = parseInt(this.azVersion.split('.')[1], 10);
        if (isNaN(azcliMinorVersion)) {
            core.warning("Failed to parse the minor version of Azure CLI. Assuming the version is less than 2.69.0");
            azcliMinorVersion = 0;
        }
    }
    catch (error) {
        core.warning("Failed to parse the minor version of Azure CLI. Assuming the version is less than 2.69.0");
    }
    
    if (azcliMinorVersion < 69) {
        args.push("--username", this.loginConfig.servicePrincipalId);
    }
    else {
        args.push("--client-id", this.loginConfig.servicePrincipalId);
    }
    await this.callCliLogin(args, 'user-assigned managed identity');
}

Maintains backward compatibility while supporting the new parameter format.
