#163 Update dependencies and Github templates.

[kalbfled]

Description

I upgraded the pyyaml package and the testing packages of note to Dependabot. Among the files in setup.py, only pyyaml and mistune are pinned to specific versions, and we are not updating mistune.

I also updated Github templates consistent with the changes made for other repositories.
