[compiler][snap] Fix test filter + watch mode

Accidentally broke this when migrating our test runner to use the bundled build https://github.com/facebook/react/pull/32758

The fix is pretty simple. File watcher should listen for changes in `packages/babel-plugin-react-compiler` instead of `cwd`, which is now `packages/snap`.

-# react_diagnostics
-
-Types for representing compiler diagnostics. Includes a general-purpose representation
-of diagnostics with related information which can be converted into `miette::Diagnostic` to exploit miette's pretty printing of errors. 
-
-Unlike miette, lsp_types, and other diagnostic libraries, the error severities match
-React Compiler's semantics. The intent is that a given diagnostic may be displayed as
-an error, warning, or not displayed at all depending on the context in which the 
-compiler is being used. For example, an ESLint plugin powered by React Compiler may ignore
-InvalidSyntax diagnostics, whereas the regular compiler may report them as errors.

-# react_estree
-
-This crate is a Rust representation of the [ESTree format](https://github.com/estree/estree/tree/master) and
-popular extenions including JSX and (eventually) Flow and TypeScript.
-
-This crate is intended as the main interchange format with outside code. A typical integration with React Compiler
-will look as follows:
-
-1. Host Compiler parses into the host AST format.
-2. Host Compiler converts into `react_estree`.
-3. Host Compiler invokes React Compiler to compile the input, which (conceptually) 
-   returns the resulting code in `react_estree` format.
-4. Host Compiler convert back from `react_estree` to its host AST format.
-
-Because React Compiler is intended to support JavaScript-based toolchains, `react_estree` is designed to support
-accurate serialization to/from estree-compatible JSON. We may also support the Babel AST format 
-(a variant of ESTree) as well, depending on demand.
