Incidents/2023-05-30 Unintentional +2 on a config patch without deployment

== Summary ==
https://gerrit.wikimedia.org/r/c/operations/mediawiki-config/+/923650 was accidentally +2'd without intent to deploy (like on a software repo rather than a config repo). This could have led to confusion for a future deployer.
==Timeline==
All times in UTC.
*05-30 10:00 https://gerrit.wikimedia.org/r/c/operations/mediawiki-config/+/923650 is +2'd
*05-30 10:01 patch was reverted by an observer.
==Detection==
==Conclusions ==
OPTIONAL: General conclusions (bullet points or narrative)
===What went well?===
* The mistake was noticed by someone else within a minute, and subsequently reverted.
OPTIONAL: (Use bullet points) for example: automated monitoring detected the incident, outage was root-caused quickly, etc
===What went poorly?===
* …
OPTIONAL: (Use bullet points) for example: documentation on the affected service was unhelpful, communication difficulties, etc
===Where did we get lucky?===
* …
OPTIONAL: (Use bullet points) for example: user's error report was exceptionally detailed, incident occurred when the most people were online to assist, etc
==Links to relevant documentation==
* …
Add links to information that someone responding to this alert should have (runbook, plus supporting docs). If that documentation does not exist, add an action item to create it.
==Actionables==
* …
Create a list of action items that will help prevent this from happening again as much as possible. Link to or create a Phabricator task for every step.
Add the #Sustainability (Incident Followup) and the #SRE-OnFire Phabricator tag to these tasks.
