chore(templates): ignore lockfiles

[MichaelDeBoey]

Just like in examples, we don't want to have lockfiles in templates either.

We're running npm/yarn/pnpm install in our CLI (both when creating & on init), so this could cause unnecessary lockfiles if the user's package manager is different from the one we included the lockfile for.

Lines 225 to 228 in a511d34

	execSync(`${packageManager} install`, {
	stdio: "inherit",
	cwd: projectDir,
	});

Lines 71 to 74 in a511d34

	execSync(`${packageManager} install`, {
	stdio: "ignore",
	cwd: initScriptDir,
	});

I also updated our default stacks for this: remix-run/indie-stack#79, remix-run/blues-stack#67 & remix-run/grunge-stack#53
