Update text for corporate designations in Name Structure Check

## To do
- [ ] Update the text

## Description

> Kaine, Jenn has found an incorrect direction in NRA (spelling errors are in yellow):
>
> We had an inquiry from a client about submitting a name that contains a “duplicate designation” as they wanted to submit a name with both English and French, but the system generates a message to the user in NRA. That the Name Structure Check wording in Name Request indicates that for corporate designations, the same designation cannot be used twice in a name, which is not entirely correct. I also found a couple of spelling errors as well. This text doesn’t speak to names that may contain the French version (or vice versa as the English version) as well, and I’m wondering if you think this needs to be updated to include this information?

> Currently it indicates, **“A name cannot contain the same designation word twice. A name can contain more than one designation word if the words are different, e.g., if you have choosen "Inc." for the desgination at the end of your name you cannot use "Inc." elsewhere in the name, but you can use "Company" elsewhere in the name.”**, as per:

> **“Only one designation word can be used in a name and it must be at the end of the name. The exception is if the name contains both the French and English versions of the name, the designation word can be at the end of each version, e.g., AB CAFE INC. / CAFE AB INC. The word “Company” or “Co” can also be used elsewhere in a name.”**
