chore(create-cloudflare): remove unused chalk dependency

[roli-lpci]

Part of #11854.

chalk is listed as a devDependency in create-cloudflare but is not
imported anywhere in the package. The color utilities used by
create-cloudflare come from @cloudflare/cli/colors, which has its own
chalk dependency. This stale devDependency was left behind when the color
code was extracted to @cloudflare/cli in #4189.

# Confirmed no chalk imports in create-cloudflare source
> grep -r "from ['\"]chalk" packages/create-cloudflare/src/
(blank)
