`netbird up` fails after `netbird down`

[synfinatic]

Describe the problem

Ran netbird down followed by netbird up on a RasPi running Linux/Debian 12. the up command failed with the errors:

$ netbird up
2024-02-23T16:01:09Z WARN client/cmd/root.go:195: retrying Login to the Management service in 1.127617486s due to error rpc error: code = Unknown desc = getting device authorization flow info failed with error: context deadline exceeded
2024-02-23T16:01:20Z WARN client/cmd/root.go:195: retrying Login to the Management service in 2.043948863s due to error rpc error: code = Unknown desc = getting device authorization flow info failed with error: context deadline exceeded
Error: login backoff cycle failed: rpc error: code = Unknown desc = getting device authorization flow info failed with error: context deadline exceeded

I diagnosed the root cause for this as being netbird up modified the /etc/resolv.conf file, but netbird down did not restore the original list of nameserver entries. Basically, the NetBird DNS server is not available when NetBird is down and so DNS resolution is failing. Manually editing the file and commenting out the line reading nameserver 100.93.254.165 fixed the issue.

To Reproduce

See above.
