Use ValidatorDef.STRING_WITHOUT_TEMPLATE_VARS_VALIDATOR

[zepumph]

I noticed this validator keeps template vars out of the PDOM, but there is no such logic for the UtteranceQueue. @jessegreenberg, this describes the weird reading block case we had last Friday where there was no error for template variables.

Should be as easy as a check in each Announcer.

Assigning to both @jessegreenberg and me for whoever gets it first.

I'm feeling pretty confident about this one! Closing
