Fix an invalid template literal in the Node file-watcher example

[rinceyuan]

The file-watcher example in nodejs/docs/examples.md escapes the backticks around the path twice, so the snippet is a syntax error if you copy it.

prompt: `The user edited \\`${relPath}\\`.`,

\\ is an escaped backslash, so the backtick that follows it terminates the template literal, and ${relPath} then sits outside any string.

Proof

$ node -e "const relPath='src/app.ts'; eval('\`The user edited \\\\\\\\\`\${relPath}\\\\\\\\\`.\`')"
SyntaxError: Unexpected identifier '$'

With a single backslash it parses and produces what the example intends:

$ node -e "const relPath='src/app.ts'; console.log(eval('\`The user edited \\\\\`\${relPath}\\\\\`.\`'))"
The user edited `src/app.ts`.

Scope

One character removed from each of the two escapes, on one line. This is the only occurrence in the repository:

$ git grep -rn '\\\\`' -- nodejs/docs docs '*/README.md'
nodejs/docs/examples.md:527:            prompt: `The user edited \\`${relPath}\\`.`,

Why it was not caught

scripts/docs-validation only scans the repository-root docs/ directory — const DOCS_DIR = path.resolve(import.meta.dirname, "../../docs") — so the 54 code blocks under nodejs/docs/ are never extracted or type-checked.

While I was there I checked the rest of that directory by extracting the 12 blocks that carry imports and type-checking them against nodejs/src. After this fix, the only remaining failures are three bare object-literal fragments that end mid-structure and are not meant to compile standalone — the same class extract.ts already skips deliberately for TypeScript. nodejs/examples/basic-example.ts type-checks cleanly too.

I have not tried to extend the validation tooling to cover nodejs/docs/, since whether those pages should be in scope looked like your call.
