Missing fraction input validator.

[iamprayush]

Describe the bug
As discussed in #8671, we need to add a validator for when the Fraction Input interaction is being created. This validator should disallow numbers with more than 7 digits in the fraction.
#8671 adds validator for the learner's input. We need a validator for creator's input as well.

Additional context
An audit job to alter any existing exploration with such inputs would also need to be added.

Hi @samruddhiDharankar!
This issue also involves writing an audit job which might be a little tricky since this is your first contribution. I suggest working on a couple of starter issues and then coming back to this one.
Also, make sure to read this page so that you don't miss anything important.
Thanks!
