Fix link to FuncDeclarator

[wilzbach]

@CyberShadow any smart idea on easily verifying that all links are valid?
The ugly way would be to parse the generated HTML, create name/id lists for each file and then check all links ...

Thanks for your pull request, @wilzbach! We are looking forward to reviewing it, and you should be hearing from a maintainer soon.

Some things that can help to speed things up:

• smaller, focused PRs are easier to review than big ones

• try not to mix up refactoring or style changes with bug fixes or feature enhancements

• provide helpful commit messages explaining the rationale behind each change

Bear in mind that large or tricky changes may require multiple rounds of review and revision.

Please see CONTRIBUTING.md for more information.

Bugzilla references

Your PR doesn't reference any Bugzilla issue.

If your PR contains non-trivial changes, please reference a Bugzilla issue or create a manual changelog.

That's the way.

chmgen already does it BTW.

-> dlang/dlang-bot#44

The idea is to always "reserve" the first comment and update it with helpful information.
We are still at the beginning and it's not super helpful (yet), but this is deployed:

• hello world message
• warning about a regression PR not targeted at stable

Anyways, there's more to come.

@CyberShadow @wilzbach can you guys add a "Ddoc bug fix" label? The intent is to tag pull requests that fix ddoc errors (such as this one) but don't otherwise deserve a Bugzilla entry.

[wilzbach]

@ZombineDev You can add them yourself - click on labels on the pull requests overview list...

@wilzbach Thanks, not sure how I missed it.
