Gitea stores a page whose name has a hyphen under an escaped address
(Getting-started.-), which the shared publish workflow does not match, so
the second run tried to create the page again and got HTTP 400. Use
GettingStarted and SshAndTokens, as the wiki of TirSystem/github-action
does.
Add a wiki/ folder with a .publish marker for the shared Publish wiki
workflow, a Quality workflow (shellcheck and shfmt through the shared
reusable workflow) and a manual Release workflow that builds the release
page from CHANGELOG.md.
Set switch_case_indent for *.sh in .editorconfig so shfmt accepts the
existing case layout.
