Describe the Bug

The builtin component Code.astro doesn't set .astro-code css class to the rendered pre as it did before.

Starting from shiki v0.12, a new feature reported here shikijs/shiki#376 adds the theme name as css class. Even if the author added it as optional, in the end it's forced, see shikijs/shiki#376 (comment)

This causes the bug, as the replace logic of Code.astro doens't work anymore. This bug happens when astro build.

Important
Actually because the shiki version is pinned to v0.11, this bug doens't occur. When updated to v0.12, the bug will happen. The PR I submitted, just resolves this issue. It's retro compatible with the v0.11 so it can be merged nonetheless.
