Update peer dependency

[thecrypticace]

This should just list Prettier v3. Not v2 as well.

[hyunbinseo]

So the plugin no longer supports Prettier v2 from 0.5.x?

0.4.x seem to support both v2 and v3 according to #179

There is no mention of this breaking change in the changelog.

devDependencies:
- prettier-plugin-tailwindcss 0.4.1
+ prettier-plugin-tailwindcss 0.5.1 (0.5.4 is available)
