NOTE: This commit does NOT change content, policy, or the substance of
any written documentation that requires Fedora Council review. This
change only impacts changes related to the Antora toolchain.

This commit integrates the team directory profile that was introduced a
few years ago into the Fedora Council documentation. This makes several
common URLs used across the Fedora Council Antora component accessible
as macros. Instead of hard-coding the same URL across all of the Fedora
Council documentation, the macros can be used to more easily re-use the
same URL consistently across multiple pages.

This commit is one of several that gradually refactors the Fedora
Council documentation to properly fit into an AsciiDoc and Antora
workflow.
