Jira: DOC-5634
Draft preview: https://d5rxiv0do0q3v.cloudfront.net/DOC-5634/astra-cli/index.html

This PR updates the auto-generated command reference pages for the Astra CLI 1.0.3 release.

Steps taken to generate these docs:

1. Clone https://github.com/datastax/astra-cli.
2. Run source scripts/dev-alias.sh.
3. Use astra docgen to generate the files and overwrite them onto the old ones:

astra docgen \
  && cp build/docs/partial-nav.adoc ~/repos/astra-cli-docs/modules/ROOT/partials/ \
  && mkdir -p ~/repos/astra-cli-docs/modules/commands/pages \
  && rm -rf ~/repos/astra-cli-docs/modules/commands/pages/*(N) \
  && cp -r build/docs/commands/* ~/repos/astra-cli-docs/modules/commands/pages/

Noticed usage of via and e.g., but as you mentioned, these docs are auto-generated.
