[BUG] Enable developers to use the execution environment's filesystem when invoking components via API

[dannyroosevelt]

As a dev, I want to let my end users download a file from Google Drive for example, then upload that file to Slack. tmp storage isn't set up to handle that use case well when running components via the API today.

The right solution is probably to enable components to use the File Store instead of tmp storage (blocked by #9279), but there may be a near term solution to improve the implementation of how tmp works in this context.

This shorter term approach is done! /tmp is now supported and accessible for the actionRun API in Connect
