add twitter conversion tracking

[Findus23]

This is just an untested tag.

Unfortunately the docs only mention copying the tracking code, but without an account one can't see it.

So I took the most basic tracking code I found, but I can't test it.

Here is also another tracking code for tracking a purchase, but I don't know what it can be used for.

If someone knows more about Twitter conversion tracking, please comment.

According to Google Tag Manager the possible track-values are

but there are no google search results for them and the twitter docs don't mention them. (I can't even get them to display in English instead of German)

What do we need to test it? A twitter business or ad account or something?

[Findus23]

Honestly I have no idea what the use of this conversion code is. So most importantly I would need docs or someone who knows more about it.

@Findus23 are you still working on this?

[Findus23]

@tsteur No, as neither do I understand the docs nor have a way to test it.
