WebIDL highighting is missing

[kant2002]

Currently when run in development mode I see following message

The language "webidl" doesn't exist, falling back to plaintext.

That's because shiki does not support webidl as a language out of the box.
I see 2 options

1. Place webidl file in this repo and add integration. Fast
2. Attempt to add webidl to Shiki and wait for it to release. Probably slow.

Obviosuly there third option with going both ways. Implement 1 first, submit PR to Shiki and wait for release to happens.

FWIW, there's only one instance of webidl in the whole repo, so there are two other solutions:

3. Find a syntax language that highlights it well enough
4. Remove the webidl directive from the backticks and leave it as plaintext
