podman-desktop: switch pnpm pin back to pnpm_10

The hard pin to pnpm_10_29_2 worked around a lockfile regression in pnpm
10.29.3+ that broke electron-builder. electron-builder fixed it in
26.8.2,
which podman-desktop has shipped since 1.26.0, so pnpm_10 builds cleanly
on the current 1.27.2 tree.
Switch the pin back to pnpm_10 and re-enable the pnpm bump in the update
script.
