Bad advice if curvenote finds multiple config files

[fwkoch]

If you have both curvenote.yml and myst.yml in a directory, curvenote will not know which to use. However, it gives very bad advice... removing your token won't fix things, it will only give you another problem to resolve.

ouch, overall should we just prefer curvenote.yml over myst.yml and warn on that?
i'm not sure if that's easy to do

Defaulting to one rather than erroring would be easy to do over in myst: Just return configs[0] here, even when multiple are present - https://github.com/executablebooks/mystmd/blob/main/packages/myst-cli/src/config.ts#L38

However, the bigger thing to address for this specific issue is the logging here when there's an error initializing the session: https://github.com/curvenote/curvenote/blob/main/packages/curvenote-cli/src/session/utils.ts#L36 - I think for that, we just remove the catchall log message, and make sure we log useful messages in the right place.

#570 removes the bad advice in this case. My opinion is we just leave the error on multiple config files - I think this is a super unlikely thing for a user to hit, and if they do, relatively easy to fix.
