storage-path is required (v2 branch)

[yamcodes]

The v2 branch's README implies that storage-path is optional.

However, using action without supplying storage-path (for example when storage-provider is set to local) produces this error:

Either the README must specify that it is required, or there should be a code change making this parameter optional when storage-provider is set to local, like the TRRC docs specify.
