feat: add |||- chomped text block syntax

[vergenzt]

Resolves #289!

Was pretty easy to add as you can see. 🙂

Let me know if you have any concerns or feedback!

Only part I'm not sure of is the changes to doc/third_party/MathJax-2.7.2/unpacked -- it looks like like at

jsonnet/doc/_layouts/base.html

Line 22 in 9952fc5

<script type="text/javascript" src="/third_party/MathJax-2.7.2/MathJax.js"></script>

we link to the root "packed" version of MathJax.js, but I can't figure out to re-"pack" the unpacked code. 🤔 I'm also not sure how critical it is though. 🤷🏻‍♂️

Note: I'm working on a companion PR to google/go-jsonnet too.

Is there any estimate on when this will get merged (and released)?

Hi. Thanks for your contribution, and sorry for the delay in processing it!

The MathJax change is not needed - that operator list is nothing to do with jsonnet, so it shouldn't be updated for this change. As far as I can tell, those operators originate from the MathML spec - https://www.w3.org/TR/MathML/appendixc.html (the existing triple-pipe fence was added to the table in mathjax/MathJax@bf862f6#diff-8e4e61c67ba8f00ac92875cb211f3a2ec8eef705f71d232d4d3dcb014d0517c0)

Yay thank you!!!
