Update method showModeratorEvent to use playerNameFromCommandSource instead of sender

[magge-faf]

Improved the moderation workflow by having concise one-liners, instead of detailed event dumps. Additional info will be refactored later.

The output-decision was voted in Zulip by the Moderators, how we should introduce that basic feature.

Preferred:

instead:

Outline:

• Changed sender to playerNameFromCommandSource for method showModeratorEvent
• Updated commonsVersion for faf-commons to make above method available

Info:

sender was replaced with playerNameFromCommandSource or playerNameFromArmy in that commit

Both represent the player name, I went with playerNameFromCommandSource, because it should be more resistant against manipulation.

Fixes #205

I am unable to add Reviewers (top right in GitHub, gear-wheel is missing next to Reviewers). I think it is permission related? Well, I go with tagging again:

Thank you for reviewing @Brutus5000, @Sheikah45

Could you release an officially Mordor version with all the recent changes to make those features accessible for every Moderator, please?
