Change formatting in the "Catalog queries" doc

Current syntax uses definition lists [1] from mkdocs-material.
However it relies on a tailing space after a colon to work.
E.g. the whole line becomes `: ` and it is prone to errors because:
1. It is easy to overlook a space which is part of formatting.
2. Many editors remove tailing spaces at the end of lines.
3. We will be adding more definition lists into this docs
   to explain placeholders such as `<package_name>`.
   With nested definition lists markdown of this document
   going to be very difficult to manage.

This commit switches from definition lists to unordered list.
