feat: add cache-write input for read-only cache mode

Add a 'cache-write' input (default: true) that controls whether the cache
is saved at the end of the workflow. When set to 'false', the action will
restore cached dependencies but skip saving, providing a read-only cache
mode.

This is useful for preventing cache poisoning attacks from untrusted PR
builds while still benefiting from cached dependencies.
