doc: buffer TOC incorrectly contains brackets

[mscdex]

• Version: master, v6.x
• Platform: n/a
• Subsystem: doc

In the buffer doc TOC there is an entry called 'What makes [Buffer.allocUnsafe()] and [Buffer.allocUnsafeSlow()] "unsafe"?'. The brackets there should not be visible. The brackets do not exist in the v4.x docs. If I had to take a wild guess I would say the brackets were introduced when the 'deprecated' tags were added to every doc pages' TOC, as that is the immediate obvious difference between the buffer doc TOC in v4.x and v6.x/latest.

Reverting fcee4d4 does not fix it. Must be something else.

I found a way to fix the HTML generation so that the links will be visible. But the problem is, each and every part of the link will be pointing to different things. "What makes" will point to the actual section, allocUnsafe and allocUnsafeSlow will point to their corresponding sections, "and" and "unsafe" will point to the actual section. That would be quite confusing, I guess.
