Support reference-style Markdown links in "surround with" about idea-concordion-support

Hello,

I believe this is implemented by Surround with Concordion expression.
It does not have initial hot key binding and can be found using Ctrl+Shift+A or find action menu

Hi Ievgen

When I use Surround with Concordion expression on a text block Selected Text it generates [Selected Text](- "").

As far as I can tell, there's no way to ask it to generate the reference-style link style:

[Selected Text][]
⋮
[Selected Text]: - ""

Where the [Selected Text]: - "" portion could be anywhere, but in my experience would normally be at the end of the example or end of file. For tables, it would normally be after the table.

If I then tried to generate a link to a subsequent identical Selected Text block of text, it should just generate:

[Selected Text][] and reuse the existing declaration.

An alternative format is:

[Selected Text][id]
⋮
[id]: - ""

where id can be any valid identifier.

I realise this is asking a lot, so don't bother if it's too complex. I tend to use this style maybe 20% of the time.
