fix: add pnpm build approvals for sharp and workerd in Cloudflare deployment add-on

When using pnpm v11, creating a Cloudflare-deployed project fails because
`wrangler` transitively depends on `sharp` and `workerd`, which have build
scripts that are not listed in `pnpm.onlyBuiltDependencies`.

Add these entries to both the React and Solid Cloudflare host `package.json.ejs`
templates so they are merged with the base approvals at project creation time.
