feat: a new simple (correct) test that may break some accepted solutions

[barabo]

Some of the community solutions incorrectly try to locate STOP codons from input and strip anything that follows the first STOP codon. This is a neat idea, but if the regex is not anchored, or if it does not align to groups of 3 - it's possible that a valid pair of codons (AUGAUG, for example,) creates a pattern that can cause the regex mis-identify a sequence as a STOP codon when it is not (UGA, in the previous example).

  AUGAUG
   ^^^ - not a STOP codon

  UUAAUG
   ^^^ - not a STOP codon

Summary

A couple of the accepted solutions to this problem have a subtle bug that the tests are not catching. This PR corrects that by putting a simple test in place.

Bonus

I noticed that the contractions in the test descriptions were not rendering correctly, so I changed them to non-contractions.

Thank you for the PR! However, this exercise is a practice exercise so any changes must be applied to the problem specs then synced. Please read https://exercism.org/docs/community/being-a-good-community-member/suggesting-exercise-improvements#h-practice-exercises

[barabo]

Thanks for the pointer! I opened exercism/problem-specifications#2458 - for cross referencing.

Do you want to submit the jq version of the test now? Use bin/configlet sync and bin/generate_tests

[IsaacG]

Woops. I did a sync PR. Feel free to ignore.

[barabo]

I'm happy to revive this PR if the changes are still wanted / needed.

[glennj]

Isaac created #243. Do you want to review that, or try to do it yourself?
