[serviceconnector-passwordless] Fix postgres command argument name

[avanigupta]

---

Updated internal argument for az postgres flexible-server db show command from --database-name to --name.
This was broken due to a recent breaking change in postgres CLI module: Azure/azure-cli#33343

This PR also pins the minimum CLI version to 2.87.0 - which contains the Postgres breaking change.

Hi @yonzhan @yanzhudd, can we include this change in the next CLI release? Its a small change so should be a quick review.
This is blocking one of our customers and we are hoping to release this as soon as possible.
