[New Exercise] AWK: Phone Number, Isogram?, Bank Account?

Hi team,

I’ve ported new exercises to the AWK language:

Phone Numbers:

[?] Isogram:

[?] Bank Account

I’m not sure how it is better to implement the isogram for AWK.

The Bank Account is also questionable because it is not possible to use concurrency in AWK. So I’ve implemented all tests except the last one.

I think we should forgo Bank Account

Yeah. It has a low value for the AWK track.

The Phone Numbers seem a good fit for the AWK track.
I’m not sure about Isogram.
It is also possible to implement it differently.

P.S. All bats tests for the exercises were generated automatically by script.

Agree about bank account.

Would you like to add that in a PR into the bin directory?
