🐛 Bug: pnpm dedupe --offline doesn't always have available packages

Bug Report Checklist

• I have pulled the latest main branch of the repository.
• I have searched for related issues and found none that matched my issue.

Expected

Back in #1610 -> #1611, I'd switched package dedupe checks to pnpm dedupe --offline as a performance improvement. I'd thought that in theory all packages needed for this should be available. It's always run after a pnpm install, after all:

create-typescript-app/src/blocks/blockPnpmDedupe.ts

Line 34 in c179a7e

cleanupCommands: ["pnpm dedupe --offline"],

create-typescript-app/src/blocks/blockPackageJson.ts

Lines 93 to 101 in c179a7e

	scripts: [
	{
	commands: [
	offline ? "pnpm install --offline" : "pnpm install",
	...addons.cleanupCommands,
	],
	phase: CommandPhase.Install,
	},
	],

Actual

When running on existing repos in transition mode, I've started to see errors like:

■  The pnpm dedupe --offline script failed. You should re-run it and fix its complaints.
