feat: retrieve pull-secret using Red Hat SSO account

[dgolovin]

Fix #207.

This PR adds:

1. Dependency to Red Hat Account extension
2. Information message request how to configure pull-secret: using RH SSO account or doing it manually
   
3. Account Management API call to retrieve pull-secret and use it during first start

Considered other implementation options:

1. Show Quick Picks instead of info message
2. Always do it with Red Hat Account and use manual input as backup. The problem is when login sequence is started there is not way to cancel it.

Works for me but I'm wondering we should enfore SSO use as manual retrieval is too complex. @slemeur WDYT ?

[slemeur]

Yes, we should enforce the use of SSO.
We could keep an option if the user wants to bring the pull secret - but that should not be the default path.

This issue containers/podman-desktop#6632 should also be fixed to make workflow better. Right now the browser just pops up and one has no idea why.

The option already exists - pointing to file with pull-secret in extension settings.
