Add @ianvs/prettier-plugin-sort-imports to html transform compat list

[zivenger]

When using this plugin together with @ianvs/prettier-plugin-sort-imports, the two plugins conflict on .vue files depending on their order in the Prettier config.

Following tailwindlabs/prettier-plugin-tailwindcss's recommended placement (placing it last), the sort-imports plugin won't take effect on .vue files. Reversing the order causes this plugin to stop working instead.

The root cause is that the vue parser lives under the html transform, whose compatible list only includes prettier-plugin-organize-attributes — missing @ianvs/prettier-plugin-sort-imports. The js transform already has it, which is why .ts files work fine.

This PR adds @ianvs/prettier-plugin-sort-imports to the html transform's compatible list, resolving the compatibility issue for .vue files.
