DEVX-118: fix: use Gitea wiki dash-marker filename convention

Gitea appends a ".-" suffix before ".md" for wiki page titles that
contain dashes, to distinguish literal dashes from space-to-dash
conversions. For example, "Getting-Started" becomes
"Getting-Started.-.md", while "Architecture" becomes "Architecture.md".

Previously the code wrote "Getting-Started.md" which Gitea couldn't
recognize as a valid wiki page, causing verification to fail with
"page not found" for 15 of 21 pages.

Also force-push to handle concurrent CI runs that may have pushed to
the wiki repo between our clone and push.
