Include registry_types in more status reports

[mbg]

Currently, the registry_types field in status reports is only populated by the start-proxy action. However, other steps such as init and analyze have access to the registry types via the CODEQL_PROXY_URLS environment variable. It is useful for us to be able to see at a glance when init or analyze steps benefit from configured registries.

This PR updates the createStatusReportBase function to try and parse the contents of CODEQL_PROXY_URLS when it is set to include the unique registry types in the status report when possible.
