Update error messages referring to array front\back to first\last

@bradcray helpfully noticed that I forgot to update error message when I submitted this PR that renamed array's front\back methods to first\last: Array module review: replace front()\back() with first\last by stonea · Pull Request #18256 · chapel-lang/chapel · GitHub

This PR updates the error messages and associated tests.

I've run this change through paratests and searched the array tests and ChapelArray.chpl files for instances of front() and back() to try and find other error messages that may have slipped through.

No review conducted as this change seems trivial \ low risk enough.
