feat: demo now runs under a temp HOME directory.

[daidoji]

Adjusted demo so that the Alice and Faber wallets are written to a temp directory created at demo runtime (via setting the HOME env variable in the script) rather than using the home directory of the user running the demo.

Fix #1430

[TimoGlastra]

Hey @daidoji, thanks for the PR!

Is the reason to put the demo under a temp directory because of the issues with re-running the demo? I have a PR that should fix this: #1439.

Or do you want to keep the data separate? For Indy SDK you can change the path using the storage_config: https://github.com/hyperledger/indy-sdk/tree/main/wrappers/nodejs#createwallet--config-credentials----void (not sure if this is exposed in the interface), and for Askar you can change the baseDataPath in the file system: https://github.com/hyperledger/aries-framework-javascript/blob/main/packages/node/src/NodeFileSystem.ts#L28-L29

@TimoGlastra cool, yeah if your PR covers it I can just withdraw this one. The idea was just to keep whatever wallet state from the demo out of any indy wallet credentials I might have in my home directory. Using HOME was the only way I could figure out how to do that because I didn't find what you linked.

How would I check that these are available in the interface and maybe I could update the documentation for future generations. Does that #1439 PR cover changes to get the demo working again?

[TimoGlastra]

@daidoji now that #1439 is merged, could you check if it's fully working again in the main branch? Otherwise we can add the changes to this PR to fix it

@TimoGlastra I'll close this because it isn't wiping the Indy VDR wallet anymore but the demo is broken again or something is up. I think its trying to load libindy and failing. I'll open another issue though.
