New db config.edn don't include any of the file graph keys or comments.
Previously all comments were confusingly left lying around.
Also moved conversion of imported config.edn so that CLI can use it.
Also temporarily moved one dep to
https://github.com/nextjournal/nbb-test-runner/pull/2 until the PR is
merged
since they are the future. Leave example disabled by default as it's
not important to have :sort-by-priority enabled by default and working
for both file and db graphs
closes LOG-3042. Moved :default-queries to default-config as this allows
for any future fix to automatically update for a user. There's also a
breaking change with this config key from :block/journal? so moving this
to default-config makes the migration easier e.g. just tell users to
remove the config key
so it can be used outside Electron e.g. when creating graphs from CLI.
Put a symlink in the old templates/config.edn location to make new
location easier to find but it's not needed for anything to work
