fix(odd): stop polluting console log with "▶ Object" (#20111)

# Overview

The JavaScript console for the ODD was filling up with log messages of:
```
[app//opt/opentrons-app/resources/app.asar/ui/assets/index-XXX.js] debug: Received action from main via IPC
--------------------------------------------------
▶ Object
```
which is not very helpful.

This PR is a small tweak to inline the action into the log message so
that you can see it without clicking on `▶ Object`, decluttering the
console.

## Risk assessment

Low.
