Vercel CLI build for Remix fails on Windows because of ':'(colon) in path

Remix treats a dynamic route parameter as a :-prefixed segment in path as in foo/:bar.

When vercel build, writeLambda() creates a symbolic link on that path but Windows doesn't permit : in filename, so it fails:

Error: ENOENT: no such file or directory, symlink '..\404.func' -> 'path-to-project\.vercel\output\functions\foo\:bar.func'

The simplest solution might be:

// before
const dest = join(outputDir, 'functions', `${path}.func`);

// after
const dest = join(outputDir, 'functions', `${process.platform === 'win32' ? path.replace(':', '$') : path}.func`);

but it has too much overhead for other irrelevant cases.

Hope it'be solved seamlessly.

Start in packages/cli/src/util/build/write-build-result.ts at writeLambda(), where the function output path is assembled. Reproduce the Windows vercel build failure for a dynamic route containing a colon, then verify that the generated function path uses a Windows-safe representation and that the build completes successfully.
