Code Freeze salon topic is overly verbose

[jewel-andraia]

harold set the channel topic: ❄️ CODE FREEZE -- No deploys (DEPLOYS ARE ON HOLD - deploy freeze for Pre-Holiday Bugfixes is now in effect. More details on http://tiny.cc/06kzcz (Mr. Freeze: https://gph.is/1eMBXxy)) | @andytuba has the :conch: | no active deploys | queue

This topic gets so long that it's a little unusable, particularly if anyone is queued.

❄️ CODE FREEZE -- No deploys

This preamble comes from code:

harold/harold/plugins/deploy.py

Lines 278 to 281 in 7948fb7

	if self.current_hold_type == DeployHoldType.code_freeze:
	status = ":snowflake: CODE FREEZE -- No deploys (%s)" % self.current_hold
	else:
	status = ":no_entry_sign: deploys ON HOLD (%s)" % self.current_hold

That preamble could be reduced to:

:snowflake: DEPLOY FREEZE

DEPLOYS ARE ON HOLD - deploy freeze for Pre-Holiday Bugfixes is now in effect. More details on http://tiny.cc/06kzcz (Mr. Freeze: https://gph.is/1eMBXxy)

This current_hold messaging probably comes from the Google Apps Script which backs the Google Form. In the context of the salon topic, there are redundancies which could be improved.

The current_hold message sent by the script could be reduced to the bare minimum. Although I mourn the loss of the "Mr. Freeze" styling, I'd favor simplicity and functionality over style.

For example:
