As a Wikidata editor, I would like to be able to read ShEx more easily.
We do not have syntax highlighting when viewing EntitySchema pages – just a dull, grey `<pre>`.
Note that this is distinct from syntax highlighting when //editing// the pages (T224962).
Pygments support for ShEx was merged recently-ish ([pull request](https://bitbucket.org/birkenfeld/pygments-main/pull-requests/831/add-lexer-for-shexc)), but has not made it into any release yet. And once it’s released, we’ll presumably have to wait for [Extension:SyntaxHighlight](https://www.mediawiki.org/wiki/Extension:SyntaxHighlight) to pull in the new Pygments version.
GIVEN a Entity Schema
WHEN in view mode
THEN the ShEx code has syntax highlighting
[ ] the view mode of an Entity Schema page has syntax highlighting for the ShEx code
