docs: Remove the findRE TOC example

[whereandy]

In the documentation for generating a table of contents using findRE to grab h2's, the <a href="#{{ . | plainify | urlize }}"> will not correctly generate links for heading anchors that have non-alphanumeric characters in them, such as periods. The workaround I came up with was:

{{ . | plainify | htmlUnescape | urlize | replaceRE "([^0-9a-zA-Z\\.\\-\\s])" "" | replaceRE "(\\.)" "-" | replaceRE "(\\-){2,}" "-" }} 

Which replicated the process described in heading anchor generation.

If this is in the docs, it should be removed, not be made more complex. Adding replaceRE was maybe a mistake, but please don't add such anti-patterns to the docs.

Remove the replaceRE TOC example

There isn't a replaceRE TOC example in the (new or current) docs. Are you talking about findRE, @bep?

[bep]

I'm not talking about anything. If there isn't a replaceRE TOC example in the docs, then the thread starter must have dreamed it (which I doubt), and then this issue could be closed.

That would be a very dull dream:

You framed your response in the example of replaceRE and then said adding that function might have been a mistake. I am only asking if you still think the findRE example in the current docs needs to be removed...

[bep]

In the documentation for generating a table of contents using findRE to grab h2's...

OK, I have updated the issue title. But the relevant example is in the above.

This has been removed from the findRe example in the new docs site:
