Docs shouldn't collapse pragmas inside runnableExamples/code blocks

[metagn]

Example

template byaddr*(lhs, typ, ex) =
  ## Allows a syntax for lvalue reference, exact analog to
  ## `auto& a = ex;` in C++
  runnableExamples:
    var s = @[10,11,12]
    var a {.byaddr.} = s[0]
    a+=100
    doAssert s == @[110,11,12]
    doAssert a is int
    var b {.byaddr.}: int = s[0]
    doAssert a.addr == b.addr

auto-collapsed pragmas (at least as currently implemented) is a misfeature IMO. I keep clicking on uncollapse in docs so it ends up wasting more time that it saves in "cosmetics".
Either we disable the collapsing, or we refine the blacklist to only collapse a very short list, eg:

• raises: []
• tags: []
  and maybe a few more, but that's it
