Getting the DidYouMean::SPELL_CHECKERS.merge!( Error

Thank you for this action, I'm hoping this will save us a lot of time updating repos.
However when I try an run it I get
```
Updated .ruby-version file

My Action config
```
name: Upgrade Ruby

on:
workflow_dispatch:
schedule:
- cron: "0 0 1 * 0" # Runs Monthly

permissions:

steps:

```

Any idea what is causing this and how I can fix it?

Reproduce the workflow using Ruby 3.4.4 and Bundler 2.2.22, then inspect the failing bundler/vendor/thor/lib/thor/error.rb stack entry. The issue is done when the GitHub Action completes without the DidYouMean::SPELL_CHECKERS NameError.
