fix: Address validationError tooltip console for outputs

[KearseTrevor]

https://desire2learn.atlassian.net/browse/GAUD-7125

After reviewing all inputs that contain validationError and FormElementMixin

• All applicable elements made use of the same pattern (using announced attribute)
• Going to go with parity with other elements

Action: Add for attribute to input-text, leave announced for now

I'm open to have a quick conversation about removing the use of announced from the elements that make use of it in their validationError tooltips

• When I removed it, and trialed it out - the behaviour appeared equivalent, but I'm unsure if it is our desired behaviour in either case for Safari + VO
