as liche has been deprecated by its developer

since Rust applications are by default placed into a custom directory outside of PATH.

since those required an external base URL currently, local file existence instead is not possible. But we do not want to burst our server with hundreds of concurrent requests for now. Let's see of this feature is implemented soon, until then we stay with still functional liche.

as building it takes too long

Also fix URL glob, as "build/docs/**.html" does not match html files in sub directories, it seems.

as the previous Rust setup has been removed

... since it does not support local file checking for internal links yet: lycheeverse/lychee#21

The base URL is not suffixed with the file path, hence it is wrong as fast as sub directories are processed. It is hence required to loop through all directories and check those individually with the directory as base path each.

Remove verbose flag. It is ignored when STDOUT and STDERR are redirected.

Do not serve redirects, so we can find outdated links.

as otherwise there are too many excludes required. lychee GET requests are quite efficient, so that is not an issue.

Add further excludes, required mainly because lychee checks also URLs in code tags :(.

OpenSSL sees a problem with their certificate, browsers on Windows not. For now simply exclude it.

also to force another checks run, as I want to have it green :).
