@muzimuzhi Thanks for the fix! We're on a deploy freeze for US Thanksgiving since so many people are on vacation, but I've marked this for next week so I'll know it's good to go. 👍

Suggested change

	# Prefix all commit messages with "[docker] " (no colon, but a trailing whitespace)
	# Prefix all commit messages with "[docker]" (no colon, but a trailing whitespace)

[muzimuzhi]

The trailing space is inherited from the commit-message.prefix setting, so I think it should be kept as is.

docs/content/code-security/dependabot/dependabot-version-updates/customizing-dependabot-prs.md

Lines 165 to 167 in a0dc1f7

	commit-message:
	# Prefix all commit messages with [docker] " (no colon, but a trailing whitespace)
	prefix: "[docker] "
