### What?
Updated `docs/01-app/02-guides/package-bundling.mdx` to use
multi-package manager syntax for `next experimental-analyze` commands.

### Why?
To clarify the correct way to run `next experimental-analyze` with
different package managers (npx, yarn, pnpm), preventing common mistakes
like using `pnpx` instead of `pnpm next` for local binary execution.

### How?
Added `yarn next experimental-analyze` and `pnpm next
experimental-analyze` alternatives to the `npx next
experimental-analyze` code blocks in Step 1 and Step 4.
