Fix minor issues with bin scripts

There are a few more items regarding the bin scripts that should be addressed before release. These include:

• Fix descriptions of descriptions with the docstrings (e.g. https://git.ligo.org/lscsoft/raven/-/blob/be0d25682066c8a7a060f98f60505257a9eddfd5/bin/raven_query#L24-27)
• Add page in documentation that includes a description of the bin scripts or at least example usage.
• Change from OptionParser to ArgumentParser
