This commit is a significant refactor of all the Fedora Council
documentation into full, native AsciiDoc. This includes following
conventions commonly associated with AsciiDoc, such as the one sentence
per line convention and using more internal xref links across pages.
It also introduces explicit link anchors on all headings.

This commit is mostly invisible to the reader. All lines across the
Antora component are now written on one sentence per line, as per the
standard AsciiDoc convention. Following this convention makes future git
diffs easier to read when it comes to actual changes in meaning.

Additionally, where applicable, I updated names and titles of roles that
have since been changed, e.g. "Fedora Community Action & Impact
Coordinator" to "Fedora Community Architect".
