docs: add PGlite support

Kysely's built-in PGliteDialect uses the same introspector as PostgreSQL, so KyselyTypegenPostgresDialect works with it as-is.

 `kysely-typegen` is a **library** (not a CLI), which means you are in control of where and how to run it, and is designed to be **extensible**, easy to add support for more database dialects.

+#### PGlite
+
+[PGlite](https://pglite.dev/) is PostgreSQL compiled to WebAssembly that runs in-process. Use Kysely's built-in [`PGliteDialect`](https://kysely-org.github.io/kysely-apidoc/classes/PGliteDialect.html) with `KyselyTypegenPostgresDialect`: PGlite is introspected exactly like PostgreSQL. Because `kysely-typegen` is a library, it can introspect the PGlite instance your application already uses, which a CLI cannot do.

+npm install @electric-sql/pglite
