Add `path` arg to all commands

[gvc]

What's the purpose of this pull request?

To allow FastStore to be run from a monorepo we need to add this path argument so the FastStore CLI can locate the directory where the actual customizations are.

How it works?

After https://github.com/vtex/faststore/2366 and https://github.com/vtex/faststore/2368 this PR just adds the arg to the OCLIF command class and pass it down to the code, to be used with withBasePath.
