feat(languages): add Prisma

Prisma schema files (.prisma) get syntax highlighting, structure view and
folding from the bundled tree-sitter-prisma-io grammar, a file icon, and code
insight from @prisma/language-server (diagnostics, completion, hover,
navigation, rename, formatting), installable from the IDE.
