With GitHub's recent change to enforce stronger hash algorithms,
Circle CI was unable to clone the project repository.  By installing
our dependencies earlier in the workflow, we are able to ensure that
the AL2 git and ssh clients are used, which do support the newer
algorithms.

Details in this discussion on the Circle CI forums:
https://discuss.circleci.com/t/discussion-and-resolution-for-error-youre-using-an-rsa-key-with-sha-1-which-is-no-longer-allowed/42572
Shellcheck reported a number of warnings about unquoted references.
The specific issues were harmless given the context, but adding quotes
helps with consistency.

Additionally, shellcheck identified that the '-h' command line option
was defined twice (for --local-hostname and --help).  Drop one of
these references.

I don't see a reason for removing -h functionality here for help.

Because -h is already used for --local-hostname
