Fix all broken links

[coke]

See the error report on @finanalyst's copy of the doc site. This covers internal and external broken links, and this page should be blank.

Just fixed one in 814919d, probably several of this type:

-L<IRC|/language/glossary#index-entry-IRC>
+L<IRC|/language/glossary#IRC>

@finanalyst - how long will it take for fixes to raku/doc/main to show up on the error report?

[coke]

@dontlaugh - can we get this error report running somewhere off our CI so we can force it to regen when doing fixing/testing?

[dontlaugh]

@coke sure thing. Just point me to the code and how to run it. Is it a standalone program?

[coke]

I'm assuming it's a config option in @finanalyst 's local build of the site. I'll dig.

[coke]

@finanalyst - it's been 3 weeks - how often is the error report regenerated on your site?

[finanalyst]

@coke @dontlaugh Sorry, I missed the question to me - I guess it was when I wasn't fully functioning.

1. I manually update new-raku.finanalyst.org when something new is fixed, so it isn't picking up all the changes in Raku/docs.
2. I will update new-raku as soon as possible.
3. When docs.raku.org first went live, the error-report was producing a lot of false positives, so I stopped the production of the report on the production website

I have just created a PR to generate the error-report (it was being ignored during the build process).

[dontlaugh]

I will do a production deploy this evening so we can start collecting data.

[coke]

We should be working off https://docs-dev.raku.org/error-report or a locally generated version of this report now.
