Remove support for @prettier/plugin-php

The PHP prettier plugin doesn’t support working with inline HTML. We tried to get this to work by treating `inline` blocks as HTML and telling prettier to format them but this introduced complications and resulted in errors in some files.

The correct way for this to work is for the PHP prettier plugin to introduce support for HTML itself and, if made to work with Prettier’s multi-language support, would automatically run Tailwind’s prettier plugin to format classes.

We were trying to be too clever here but ultimately fixing the problems would be the same as adding full HTML support to the PHP prettier plugin which is not something we can tackle.
