docs: update ecosystem support from language-support docs

Add concrete Supported Ecosystems section to README based on
https://docs.socket.dev/docs/language-support. Excludes Socket Basics
ecosystems (Swift, C/C++, Julia, Dart, Elixir/Erlang).

- README: Add ecosystem table with PURL types, package managers, maturity
- index.ts: Update depscore ecosystem param description with concrete list
- manifest.json: Update tool and long descriptions with supported ecosystems

+**Supported Ecosystems**

+Ecosystem support is based on [Socket's language support documentation](https://docs.socket.dev/docs/language-support). The `ecosystem` parameter maps to PURL types as follows:
+
+| Ecosystem | PURL type | Package managers | Maturity |
+|-----------|-----------|------------------|----------|
+| JavaScript & TypeScript | `npm` | npm, yarn, pnpm, Bun, VLT | GA |
+| Python | `pypi` | uv, pip, Poetry, Anaconda | GA |
+| Go | `golang` | Go Modules | GA |
+| Java | `maven` | Maven, Gradle | GA |
+| Ruby | `gem` | Bundler | GA |
+| .NET (C#, F#, VB) | `nuget` | NuGet | GA |
+| Scala | `maven` | sbt, Maven, Gradle | GA |
+| Kotlin | `maven` | Maven, Gradle | GA |
