Change requirements.txt for compatible releases #345
Description
Currently the requirements.txt requires exact major.minor.patch versions, and Dependabot opens PRs to upgrade even patch releases.
Because we are building documentation with these dependencies, and not running a real-time/production system, we should change the requirements.txt to use the compatible releases syntax on just major.minor version. Patch releases aren't as important for us to upgrade to, as these dependencies are stable and creating working docs for the project.
