Drop references to requesting review from github-actions[bot]

[cottsay]

I'm confident that this was working as described when I wrote this tool, but GitHub's behavior appears to have changed and requesting review from the github-actions[bot] doesn't appear to do anything anymore.

We'll have to run the reviewer on push like other GitHub Actions automations.

All good.

Maybe mentioning the result of changing the action to act on push in the main README.md by changing: "When a rosdistro pull request is opened" to something like "When a rosdistro pull request is opened or updated".

If this winds up being "too spammy" we can consider magic comments a la ros-pull-request builder retest this please.

Done, thanks for the suggestion.
