Update axios version for modelserver-node and modelserver-client

[ndoschek]

Update axios version for @eclipse-emfcloud/modelserver-node and @eclipse-emfcloud/modelserver-client

Background:

is there no import for isAxiosError?

Unfortunately not with our currently used version v0.24.0. I'm not sure why we are using such an outdated version anyhow, but we use the same for modelserver-node. I guess we should consider updating this dependency (latest is currently v1.2.3) at some point for both repos, I will create a follow-up issue in emfcloud.
