chore: Optimize Covector Config

[jbolda]

Motivation

We have made some quality-of-life updates to covector. I am optimizing the config to take advantage of these changes.

Changes

• use fetch:check to query the crate API instead of command which should be less brittle
• remove extra code block backticks on publish
• remove cargo package as we no longer want to publish .crate to the GitHub Release

Note that we might be able to remove the cargo package based on our current practices, but living this in draft until we decide.
