Update radio button text on Opt-In application page - External user

[zoeyli-46]

• Opt-in application sentence needs to be updated from "Does this operation produce a regulated product listed in Table 1 of Schedule A.1 of the GGERR?" to 'Does this operation produce a regulated product listed in Table 2 of Schedule A.1 of the GGERR?'
  (Replace the "table 1" with "table 2" instead)
• small backend wording change too: meets_producing_gger_schedule_a1_regulated_product = models.BooleanField( blank=True, null=True, db_comment="Does this operation produce a regulated product listed in Table 1 of Schedule A.1 of the GGERR?", )

@patriciarussellCAS split from #2147 should this one be prioritized and put into next sprint because its a more significant inaccuracy?
