Replace broken links leading to "Help/About" and old Wiki pages

[andreoda]

The "Help/About" page got removed from the sidebar but we forgot to replace the links forwarding to it.
One example is the "guide" link when being on draft entries:

Leading to an error page: https://vocadb.net/Help/guidelines#glsongs

We need to find all and forward them to the specific VocaDB Wiki articles instead.

Additionally, the tooltip on the song edit page

Primary name (in one or more languages)

references "the guide" rather than the wiki. It's not a link though. And:

• one reference to /Help/guidelines#${section}
• song edit page validation for cover with no original
• translations referencing Help/Guidelines
• internal references to "Help" endpoint
• • especially VocaDbWeb/Views/Shared/Partials/Knockout/_EntryValidationMessage.cshtml and VocaDbWeb/Views/Shared/Partials/Shared/_DraftMessage.cshtml

Note: The old Wiki got replaced with the new Wiki, so we need to replace links leading to that as well.

We have redirects for the old wiki urls. Do you know of links that don't redirect properly (There were some reorganizations which could have broken some of them)?

@FinnRG
For example: I replaced a link on this page: https://vocadb.net/discussion/topics/637 leading to the old wiki which resulted in an error page.
-> https://wiki.vocadb.net/docs/documentation/vocadb-changelog
I already replaced it so I can not send the old link here.
I am assuming that other discussion posts and comments or entries contain broken links.

As a quick note: Both the "guidelines" link and "Frequently asked questions" links are broken on this wiki page

These links are broken on TouhouDB and UtaiteDB as well; would it be possible when fixing them to have them link to different pages for each site?
